Abstract ：
Ion-conductive materials have received much attention because of their good mechanical and electrical properties. However, their practical applications are still hampered by limited toughness and crack resistance, stemming from the restricted size of energy dissipation zones, which impacts their reliability and durability. Herein, tough fiber-reinforced composite ionogels (FRCIs) with crack resistance are fabricated by incorporating high-performance fibers into elastic ionogels to efficiently dissipate energy. The FRCIs exhibit good tearing toughness, high strength, high elastic modulus, and low bending modulus. The toughness and crack resistance of the FRCI far exceed that of previously reported gel materials, even outperforming metals and alloys. Furthermore, the electrical resistance of FRCI shows high sensitivity to deformation. Moreover, it remains undamaged after undergoing 10,000 bending cycles when fixing the artificial bone, and possesses self-sensing impact resistance, demonstrating great potential in intelligent robots and smart protective equipment.

Abstract ：
Hydrogels have received great attention due to their molecular designability and wide application range. However, they are prone to freeze at low temperatures due to the existence of mass water molecules, which can damage their flexibility and transparency, greatly limiting their use in cold environments. Although adding cryoprotectants can reduce the freezing point of hydrogels, it may also deteriorate the mechanical properties and face the risk of cryoprotectant leakage. Herein, the microphase-separated structures of hydrogels are regulated to confine water molecules in sub-6 nm nanochannels and increase the proportion of bound water, endowing the hydrogels with intrinsic anti-freezing properties, high mechanical strength, good stretchability, remarkable fracture energy, and puncture resistance. Even after being kept in liquid nitrogen for 1000 h, the hydrogel still maintains good transparency. The hydrogel can exhibit excellent low-temperature shape memory and intelligent optical waveguide properties. Additionally, the hydrogel can be assembled into strain and pressure sensors for flexible sensing at both room and low temperatures. The intrinsically anti-freezing microphase-separated hydrogel offers broad prospects in low-temperature electronic and optical applications.

Abstract ：
Hydrogel thermocells can directly convert low-grade thermal energy, such as industrial waste heat, solar heat, and human body heat, into electrical energy through redox reactions. However, existing hydrogel thermocells still face challenges in practical applications, including low output power density and poor mechanical properties. Inspired by the porous network structure of plant roots, a nanoporous hydrogel thermocell is designed through the synergy of co-nonsolvency effect and Hofmeister effect. The interconnected nanoporous network structure can serve as efficient ion-transport channels, enabling the hydrogel thermocells to achieve a high thermopower of 4.13 mV K- 1, a superior conductivity of 11.07 S m-1, and a significantly enhanced normalized output power density of 5.34 mW m- 2 K- 2. Simultaneously, the densified porous network skeleton can effectively increase the mechanical properties of the hydrogel thermocells, with a tensile strength of 9.06 MPa and a stretchability of 1460 %. After connecting 20 thermocell units in series, it can output a voltage above 2 V to directly drive electronic devices, demonstrating tremendous application potential in the fields of thermal-electric energy conversion and self-powered flexible technology.

Abstract ：
Hydrogel electrolytes have garnered extensive attention in zinc ion batteries due to their excellent flexibility and good safety. However, their limited mechanical properties, low ionic conductivity, and poor Zn2+ transference number pose significant challenges for developing high-performance zinc ion batteries. Herein, this work constructs a 3D supramolecular network capable of locking anions and active water molecules through the abundant hydrogen bonding interactions between aramid nanofibers, polyvinyl alcohol, and anions. This network synergistically enhances the mechanical properties (with a mechanical strength of 0.88 MPa and a toughness of 3.28 MJ m(-3)), ionic conductivity (4.22 S m(-1)), and Zn2+ transference number (0.78). As a result, the supramolecular composite hydrogel electrolyte can effectively inhibit dendrite growth and side reactions, facilitate interface regulation, and enable uniform zinc deposition. The Zn anode exhibits a cycle life of 1500 h at 5 mA cm(-2) and 5 mAh cm(-2), with an average coulombic efficiency of 99.1% over 600 cycles. Additionally, the Zn||polyaniline full cell maintains a high capacity retention of 78% after 9100 cycles at 1 A g(-1). The assembled pouch cells demonstrate good flexibility, deformability, and compression resistance. This work provides valuable insights into the design of high-performance hydrogel electrolytes for zinc ion batteries.

Abstract ：
Ion-conductive elastomers have emerged as ideal candidates for ionic skin and wearable devices due to their intrinsic stretchability and excellent electrical properties. Despite continuous efforts in this field, strain-stiffening, robust yet compliant ionic elastomers are still unattainable due to the limited intermolecular interactions, restricting their reliability and durability in practical applications. Inspired by the interwoven collagen fiber network and synergistic non-covalent interaction in the dermis, an immense strain-stiffening, ultra-stretchable, highly tough, and elastic ionic elastomer are reported by introducing the metal-oxygen interactions into the highly entangled network. The ionic elastomers also show intriguing self-healing ability, high adhesion, and environmental tolerance, contributed by the dynamic synergistic noncovalent interactions. The prepared ionic skin displays sensitive and stable responses to temperature and strain. This work demonstrates a new design strategy for fabricating high-performance ionic elastomers with excellent mechanical and electrical properties, showing great prospects in wearable and flexible devices. A strain-stiffening, robust yet compliant ionic elastomer is prepared by simulating the structure of the dermis. The ionic elastomer possesses immense strain-stiffening ability, ultra-stretchability, high elasticity, high toughness, self-healing ability, good adhesion, and environmental tolerance, which can realize human motion detection and temperature sensing. image

Abstract ：
Controlling the internal structure of block copolymer (BCP) particles has a significant influence on its functionalities. Here, a structure-controlling method is proposed to regulate the internal structure of BCP Janus colloidal particles using different surfactants. Different microphase separation processes take place in two connected halves of the Janus particles. An order-order transition between gyroid and lamellar phases is observed in polymeric colloids. The epitaxial growth during the structural transformation from gyroid to lamellar phase undergoes a two-layered rearrangement to accommodate the interdomain spacing mismatch between these two phases. This self-assembly behavior can be ascribed to the preferential wetting of BCP chains at the interface, which can change the chain conformation of different blocks. The Janus colloidal particles can further experience a reversible phase transition by restructuring the polymer particles under solvent vapor. It is anticipated that the new phase behavior found in Janus particles can not only enrich the self-assembly study of BCPs but also provide opportunities for various applications based on Janus particles with ordered structures. The ratio of dual surfactants is adjusted to control the formation of Janus particles with lamellar and gyroid structures. The transformation from gyroid to lamellae undergoes an epitaxial growth process. The Janus particles can be further restructured into the gyroid or lamellar structure under solvent vapor.image

Abstract ：
The rich phase behavior of block copolymers (BCPs) has drawn great attention in recent years. However, the double diamond (DD) phase is rarely obtained because of the competition between the minimization of interfacial energy and packing frustration. Here, a rod-coil BCP containing mesogen-jacketed liquid crystalline polymer is designed to acquire ordered bicontinuous network nanostructures. The reduction of internal energy originating from the orientational interaction among the rod blocks can compensate for the free energy penalty of packing frustration to stabilize the DD structure. The resulting BCP can also experience lamellae-to-DD and double gyroid-to-lamellae transitions by changing the annealing temperature. These results make the rod-coil BCP an excellent candidate for the self-assembly of ordered network structures, demonstrating great potential in nanopatterning and metamaterials.

Abstract ：
Polymer ionic conductors have shown great promise as iontronic sensors for flexible wearable devices and intelligent machines. A series of exquisitely designed hydrogels, ionogels, and ionic elastomers have good mechanical properties, such as super stretchability and high elasticity. However, most gels tend to exhibit softening or linear mechanoresponsive behavior when subjected to stress, which is completely different from the strain-stiffening behavior of the biological tissues. Therefore, designing polymer ionic conductors with good mechanical properties and strain-stiffening ability remains a challenge, which is critical in improving the reliability and durability of iontronic sensing. Here, we propose a strong/weak ionic interaction strategy to develop poly(ionic liquid) elastomers (PILEs) through the copolymerization of imidazolium ionic liquid monomers and acrylate monomers. The design allows weak ionic interactions to impart softness to the polymer network, while strong ionic interactions stiffen the network during stretching. The resulting transparent PILE possesses ultrastretchability, immense strain stiffening, good elasticity, high toughness, and puncture resistance. The PILE also shows antibacterial ability and good adhesion due to high-content charge groups in the polymer network. These combined properties make the PILE an excellent candidate for iontronic sensors, with excellent stability and sensitivity to temperature and strain, demonstrating great potential in wearable devices and human-machine interfaces.

Abstract ：
Hydrogel thermocells possess great potential in the energy conversion field as they directly absorb waste heat from the environment to drive redox reactions for continuous electricity generation. However, achieving high toughness and good elasticity simultaneously in hydrogel thermocells remains a challenge because of the inherent contradiction of energy dissipation mechanisms, severely limiting their practical applications and lifespan. To address this, a skin-like hydrogel network with a highly dense interwoven network is developed to construct hydrogel thermocells with good elasticity and high toughness. The dense network structure can effectively disperse the stress and hinder crack propagation, thus breaking the contradiction between high toughness and good elasticity. The thermocell realizes a toughness of 460 J m- 2 while reaching an elastic limit strain of 350 %, far exceeding the elasticity of previous stretchable hydrogel thermocells. Meanwhile, it exhibits ultra-low hysteresis and excellent fatigue resistance under tensile and compressive cyclic loads. Moreover, the thermocell can work stably over long periods, enabling stable voltage output even under compression, bending, and stretching. In addition, the thermocell can power the LED lamp and calculator, and can also be connected in series to form large arrays, thus rendering it an ideal power source for wearable devices.
