Abstract :
Inspired by plants and animals in nature, durable superhydrophobic surfaces have been successfully developed in the past decades. However, the practical application of these superhydrophobic surfaces suffers from poor mechanical and chemical stability after damage or longtime usage. Thus, effective silicone-based polymers are developed to prepare the intelligent self-healing and durable superhydrophobic coatings with multifunctions. The superhydrophobic coatings are composed of dynamic silicone polymers and silica nanoparticles, which can be applicable in various substrates with enhanced water repellency. The abundant hydrogen bonds and reversible B-O covalent bonds in the dynamic silicone polymers enable a strong binding force with the substrate and self-healing nature. Thus, the superhydrophobic coatings exhibit a high contact angle up to 159.3 degrees, and a low sliding angle of 6.9 degrees. Meanwhile, it displays mechanical stability against washing and abrasion damage, and chemical stability in acid and alkaline environment. Especially, it is capable of repairing the superhydrophobicity after damage due to the reversible association/dissociation of dynamic B-O covalent bonds in silicone polymers. In addition, the superhydrophobic cotton fabric shows excellent anti-fouling, self-cleaning, antibacterial property, and can be applied in oil-water separation with high efficiency. This robust and versatile superhydrophobic coatings without containing perfluoro-compounds are promising in commercial textile fishing treatment with low cost.

Abstract :
Due to its widespread availability and spontaneity, moisture electricity generation (MEG) holds unique advantages in self-powered systems. However, it faces challenges, including the limitations of relying on a single kind of power generation and insufficient output performance. Inspired by the mechanisms of water absorption of plants, this paper explores a light-moisture coordinated electricity generating hydrogel (L-MEGH) device with flexible, scalable, and highly efficient energy conversion performance, which is obtained through the UV polymerization of hydrophilic acrylamide (AAM) and phytic acid (PA) in the presence of photosensitizers. The obtained hydrogel demonstrates superior moisture absorption and remarkable electricity generation stability across a range of humidity conditions. Notably, the open-circuit voltage (Voc) of the L-MEGH increased from 0.675 to 0.838 V after the addition of photosensitizers (Erythrosin B, E) (the significant enhancement, up to 24%), and the short-circuit current (Isc) reaching 635.543 mu A. This L-MEGH can realize stable electrical output even under extreme temperatures, producing 0.5 V at -20 degrees C for 45 h. The scalable L-MEGHs (connected on-demand in series/parallel) can power various commercial electronics, including nighttime illumination, mobile phones, and health monitoring sensors. This work pioneers a sustainable power generation pathway capable of enhancing performance through the hybrid collection of multiple natural energy sources.

Abstract :
Thermochromic smart windows have been widely developed for solar regulation to save building energy. However, most current smart windows still exhibit a single responsiveness to a specific temperature, which is not conducive to daytime energy saving or nighttime privacy protection. Herein, a low-temperature response is achieved by pre-initiation of the monomer acrylamide (AAm) and acrylic acid (AA) in the synthesis of P(AAm-co-AA). Then, N-isopropyl acrylamide and AAm are introduced into P(AAm-co-AA) to form a pre-polymerized precursor solution. The liquid precursor solution can be encapsulated within two quartz glasses and synthesized in situ to prepare smart windows, which exhibit a high visible light transmittance of 84.4%, excellent solar modulation of 69.5%, and bidirectional temperature responsiveness (cold and hot). In addition, the upper critical solution temperature and the lower critical solution temperature of the hydrogel and the light transmission interval between the two temperatures can be flexibly adjusted to adapt to different climates and individual user needs. The designed smart window maintains a high light transmission within the human body's comfort temperature range. The bidirectional temperature response window achieves the dual functions of energy saving and privacy protection, making it an ideal smart window candidate with good prospects for practical applications.

Abstract :
Antifouling coatings play a crucial role in preventing the adhesion of marine organisms, bacteria, and blood, making them a primary strategy for combating biofouling in the marine industry. However, conventional antifouling coatings suffer from drawbacks such as high toxicity, limited abrasion resistance, and unstable polymer degradation rates, which can have adverse effects on the environment, economy, and human health. Thus, there is an urgent need for the development of sustainable and nontoxic antifouling coatings. This review first presents four major antifouling strategies: traditional coatings based on wettability, traditional coatings with protective structures, nontoxic coatings based on main chain degradable polymers, and nontoxic coatings combining main chain degradation with branch chain hydrolysis polymers. Second, the review provides a comprehensive overview of antifouling coatings with diverse functionalities, including antibacterial, anti -protein, anti -blood, anti -incrusting, adhesive, self -healing, and corrosion -resistant properties. Then, the application of antifouling coatings in marine environments and the medical field is thoroughly explored. Additionally, the review addresses the current challenges encountered by antifouling coatings. Finally, a forward -looking perspective is presented, envisioning future advancements in this field. By addressing these aspects, this review aims to stimulate further development and innovation in the realm of antifouling coatings.

Abstract :
Conductive hydrogels have great potential in flexible electronics due to their flexibility, excellent biocompatibility and diverse functionalities. However, most rapid-gelation hydrogels tend to manifest weak and fragile due to vigorous reaction process and poor adaptability in cryogenic environment, which severely impede their practical applications. Herein, a facile and mild strategy for rapid gelation is proposed that accelerates polymerization by generating reactive oxygen radicals via electron transfer based on the excitation of ferric phytate ligands under UV irradiation, which takes only 17 s to initiate. Interestingly, the introduced phytic acid imparts the hydrogel excellent electrical conductivity (12 ms/cm), frost resistance (- 31celcius) and improves tensile properties (elongation at break 1299 %). The hydrogel that combines the above merits inspires the construction of strain sensor for monitoring physiological activity of low-temperature environments. This study provides a simple and universal approach for the rapid preparation of antifreeze hydrogels and reinforces the focus on sustainable and high-value utilization of phytic acid in advanced applications.

Abstract :
In this paper, a stainless steel mesh coated with titanium dioxide (TiO2@SSM) membrane was developed for the separation of stable oil-water emulsions and the degradation of soluble pollutants. The TiO2@SSM membrane showed excellent underwater anti-oil adhesion performance and efficient emulsion separation under gravity (flux of 207.7 L m- 2 h-1 and efficiency of 99.58 % for toluene-water emulsion). The emulsion could also be pre-broken by microbubble flotation to enhance the separation performance of the TiO2@SSM membrane (microbubble flotation followed by separation has a flux of 369.3 L m- 2 h-1, and efficiency of 99.71 %). And the synergistic operation of separation and microbubble flotation can increase the flux to 451.6 L m- 2 h-1. The membrane showed outstanding stability and could be recycled for more than 20 times without significant deterioration, and demonstrated chemical stability for corrosion resistance test (pH 0-14). In addition, the membrane, which is easily modified with silver nanoparticles, achieves improved photocatalytic degradation properties (efficiency from 58.8 % to 88.7 %) and microbubble flotation effect (flux of 613.4 L m- 2 h-1). This work provides a rational strategy for the preparation and optimization of inorganic functional membranes for effective emulsion separation and dye degradation, and demonstrates promising applications of the separation and purification in oilcontaining sewage and wastewater remediation.
