Abstract ：
LED curing technology makes up for some drawbacks of UV mercury lamps with its merits of no ozone emission and low energy consumption, and gradually replaces traditional UV mercury lamps in numerous fields. Nevertheless, a solitary LED curing coating struggles to fulfill the requirements in terms of curing depth, curing chroma, and comprehensive performance. Based on these, four types of polyurethane acrylate (PUA) coatings were fabricated through two-step synthesis and LED/moisture dual curing technology using cycloaliphatic isocyanate (IPDI), aliphatic isocyanate (HDI), monofunctional acrylate (HEMA), and trifunctional acrylate (PETA) as the primary raw materials. The dual curing system integrates the advantages of LED curing and moisture curing, and mitigates the shortcomings of incomplete curing and poor comprehensive performance of single LED. The experimental results show that these four dual-curing coatings show a certain degree of optimization in comprehensive properties such as curing properties, thermal properties, mechanical properties, and coating properties. In particular, the dual-curing coating prepared with HDI as the hard segment and PETA as the endcapping agent has a surface drying time of only 5 s. After dual curing, the gel content, water contact angle, tensile strength, shear strength, hardness, and adhesive force of the sample can respectively reach 97.8 %, 112.4 degrees, 17.26 MPa, 3.7 MPa, 58.5 Shore D, and 5 B. Additionally, the coating also exhibited outstanding solvent resistance, with the absorption rates of 0.35 %, 8.42 %, 1.35 %, and 1.16 % respectively after 48 h immersion in water, ethanol, 10 wt% NaOH, and 10 wt% HCl solutions. It is also notable that the curing depth of the dual-cured coating can reach 8.96 mm, which is significantly higher than the 3.76 mm of the single light curing, and the colored curing is complete. Four kinds of coatings can be selected and customized in accordance with diverse application requirements, which is of great significance for the further development of environmental protection coatings and holds substantial practical value in industrial production.

Abstract ：
Lignin-containing cellulose nanofibers prepared from sugarcane bagasse was used as the substrate to fabricate the superhydrophobic membrane for oil-water separation. The superhydrophobic membrane with a water contact angle of 159.5 degrees was obtained by a facile dipping method based on triclorocadadecylsilane (OTS). The lignin retained in the membrane not only enhanced the hydrophobicity of the membrane, but also contributed to the performance of oil-water separation. When the content of lignin reached 17.53 %, the separation efficiencies of the membrane for diesel and dichloromethane could reach 96 % and 86 %, respectively. Meanwhile, the membrane also showed good oil separation flux up to 716.4 L/(m2 & sdot;h) for dichloromethane, and good recyclability, presenting a promising oil adsorbent in oil spill recovery and environmental protection.

Abstract ：
Due to the fact that single UV-cured coatings frequently fail to fulfill the requirements in terms of depth and chroma, and do not reach the ideal state in terms of comprehensive performance. In order to solve these painpoints more effectively, the sulfhydryl-modified castor oil (COME) was successfully synthesized by introducing beta-mercaptoethanol onto the plant-based material castor oil (CO) through the thiol-ene clink reaction. Subsequently, the synthesized polyurethane acrylate prepolymer (COPUA), monomer, photoinitiator and thermocuring agent were used as A component, and COME was used as B component. The two were mixed evenly according to a certain proportion, and the modified castor oil based polyurethane acrylate (COMEPUA) coatings were fabricated by UV/thermal dual-curing technology. Based on a series of performance test outcomes, the coating demonstrates excellent comprehensive properties, encompassing mechanical properties (where the shear strength, tensile strength, elongation at break, and hardness can respectively reach 5.26 MPa, 9.92 MPa, 132.55 %, and 47.77 Shore D), coating properties (where the absorption rates after 72 h immersion in water, ethanol, 10 wt% HCl, and 10 wt% NaOH solvents are respectively 0.66, 17.98, 1.89, and 0.71 %, and the volume resistivity and breakdown voltage are respectively 1.74x1016 Omega & sdot;cm and 10 KV) and curing properties (where the curing depth can reach 9.82 mm, which is significantly higher than 3.51 mm of single UV curing, and the colored curing is complete). It can exert protective functions such as anti-corrosion, anti-fouling, and insulation on circuit boards, electronic packaging, and device surfaces, and holds great potential in the application of coating materials.

Abstract ：
The photoresponsive adsorption materials are of great significance to the light controlled release performance of pollutants and the development of green regeneration of adsorption materials. A photoresponsive cellulose based imprinted adsorbent（Cell-AB-MIP）was synthesized by surface-initiates atom transfer radical polymerization （SI-ATRP） using cellulose as raw material，azobenzene derivatives as functional monomers，and the typical pesticide residues 2，4-D as template. The synthetic conditions were optimized by single factor experiment ，and the structure and performance of the material was analyzed by some characterization methods. The results show that the surface of Cell-AB-MIP contains abundant functional groups（—COOH，N=N，etc.），which have a high specific recognition effect for 2，4-D. The introduction of azobenzene group makes Cell-AB-MIP have excellent photo-induced regeneration performance. The azobenzene group on Cell-AB-MIP surface changes from trans-configuration to cisconfiguration under UV irradiation，then changing the binding affinity of adsorbent for pollutants，thus realizing green regeneration via UV-light. The desorption efficiency can reach 72. 22% in methanol medium under UV light irradiation. After 5 times of cycle，the adsorption percentage to 2，4-D still remains 83. 47%. The analysis results of SEM and EA confirm that the adsorbed pollutants can be separated from the surface of the adsorbent after UV irradiation，completing the regeneration process. © 2024 Beijing Institute of Aeronautical Materials (BIAM).

Abstract ：
Mulch films allow for efficient crop production, yet their low recovery after use causes severe microplastics (MPs) pollution in agricultural soils. MPs in agricultural environments undergo complex ageing processes, which can alter their interactions with coexisting neonicotinoids and result in unpredictable ecological risks. Here, polyethylene (PE) and polybutylene adipate terephthalate (PBAT), typical mulch films, were chosen for the preparation of PE-MPs and PBAT-MPs. The adsorption of two common neonicotinoids, imidacloprid and dinotefuran, by the two MPs and their joint toxicity were examined. We found that the specific surface area of PBAT-MPs (7.59 m2 g−1) is greater than that of PE-MPs (2.83 m2 g−1), which results in a greater adsorption capacity for neonicotinoids. Additionally, ageing increased the adsorption capacity of MPs for neonicotinoids by 37.50–40.68 % for PBAT-MPs and 44.23–72.34 % for PE-MPs. This enhancement is attributed to the introduction of additional oxygen-containing functional groups on the MPs' surfaces, which can form hydrogen bonds with the amino groups in imidacloprid and dinotefuran. Furthermore, compared to single MPs and neonicotinoids, stronger inhibition in the growth of Escherichia coli and the germination of lettuce seeds was observed when they coexisted. This study highlights the importance of assessing the interactions between MPs and neonicotinoids and their joint toxicity, thereby improving our understanding of the potential risks of MPs towards the agricultural ecosystems. © 2024 Elsevier B.V.

Abstract ：
Polymer matrix composites with excellent thermal management performance have emerged as remarkable materials in the realms of microelectronic devices and wireless communication technologies. However, achieving high thermal conductivity in most composites often requires a high filling load, which will compromise other desirable properties. Herein, utilizing physical foaming and vacuum infiltration methods, we introduce a 3D honeycomb composite consisting of surface-hydroxylated hexagonal boron nitride (OH-BN) and epoxy. The 3D OH-BN honeycomb foam in the composite features a lightweight design (0.33 g/cm3), high strength (7178 times its own weight) and prominent heat transfer performance. Significantly, these composites achieve notable thermal properties, including high through-plane thermal conductivity (2.073 W m- 1 K-1) and relatively low thermal resistance (0.995 degrees C/W) at a reduced filling load (17.2 vol%). In comparison with pure epoxy, the through-plane thermal conductivity is enhanced by an impressive 894 %, while the thermal resistance is reduced to 1/9.4 of that observed in pure epoxy. Besides, the 3D honeycomb composites combine outstanding mechanical performance, low dielectric properties and excellent insulation, underscoring their potential in the field of thermal management applications in microelectronic devices, wireless communication systems and integrated circuits.

Abstract ：
Isophorone diisocyanate (IPDI) as reactive compatibilizer was introduced into poly(butylene adipate terephthalate) (PBAT)/polylactic acid (PLA) blend by melt blending and extruded into blown films. The effect of IPDI content on the phase morphology, crystallization behavior, mechanical, thermal and barrier properties of PBAT/PLA/ IPDI blended films were investigated by Fourier transform infrared spectroscopy (FT-IR), scanning electron microscope (SEM), differential scanning calorimeter (DSC), universal tensile testing machine, thermogravimetric analyzer (TGA) and water permeability tester. Results demonstrate that the —NCO groups of IPDI can chemically react with PBAT and PLA to form copolymer, which reduces the particle size of PLA dispersed phase and leads to indistinct interface between the two-phase, effectively improving the interfacial compatibility between PBAT and PLA matrix. With increasing the IPDI content in PBAT/PLA/IPDI films, the crystallization ability of PBAT matrix and tensile strength increase, whilst the water vapor barrier performance increases first and then decreases. When the mass fraction of IPDI is 0.5%, compared with the pristine PBAT/PLA film, the PBAT/PLA/IPDI packaging film shows 74.2% and 28.6% enhancement in tensile strength on the transverse direction and machine direction, respectively, maintains decent breaking elongation of 790% and 244%, meanwhile, 38.2% reduction in water vapor permeability coefficient, which suggests the balanced overall mechanical and water vapor barrier properties. © 2023 Chengdu University of Science and Technology.
