Abstract ：
UV curable coatings have been widely used for their advantages of environmental protection and high curing efficiency. However, there are also some problems in the use of UV curable coatings, such as poor light transmission of colored coatings, shadow parts are difficult to accept light and can not be cured. In order to solve the problems existing in the curing process of UV curable coatings, the establishment of UV/ moisture dual curing system can effectively solve these problems. Using castor oil (CO), polytetramethylene ether glycol (PTMEG), isophorone diisocyanate (IPDI), hydroxyethyl methacrylate (HEMA) and tetrahydrofuran acrylate (THFA) as raw materials, a series of polyurethane prepolymers were synthesized by structural design and a series of UV/ moisture dual-curable coatings were prepared. The experimental verification, UV/ moisture dual curing system coating, not only solves the problem of traditional UV coating curing, and has better performance than UV coating, coating curing dual curing coating has excellent heat resistance and mechanical strength, tensile strength up to 8.4 MPa, small volume shrinkage, excellent weather resistance. This is a curing strategy for UV coatings that cannot fully accept UV light, and provides a new idea for the preparation of new environmentally friendly coatings by bio-based materials.

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 ：
Janus membranes, characterized by asymmetric wettability, have demonstrated exceptional potential in unidirectional oil transport and oil/water separation. Nevertheless, conventional fabrication strategies relying on bilayer/multilayer composites frequently encounter compromised separation performance due to weak interfacial binding and poor pore connectivity. Herein, we propose a monolayer biodegradable Janus membrane through electrospinning followed by plasma modification. Results indicate that the Janus membrane exhibits pronounced surface wettability contrast, with air-water contact angles of 36.3 degrees (hydrophilic side) and 138.8 degrees (hydrophobic side), coupled with underwater oil contact angles of 151.8 degrees (superoleophobic) and 67.5 degrees (oleophilic), respectively. The Janus membrane achieved 99.28 % separation efficiency and a maximum flux of 2779.9 L m-2 & sdot;h-1 across diverse oil/water mixtures. Notably, Laplace pressure gradients arising from the wettability asymmetry drive unidirectional oil transport from the hydrophobic to hydrophilic interface, enabling continuous oil harvesting in prototype spill recovery systems. Furthermore, the membrane demonstrates full biodegradability under industrial composting conditions (97.67 % biodegradation rate after 90 days), addressing the persistent microplastic pollution caused by conventional non-degradable membranes. This work pioneers a structurally integrated, eco-friendly Janus membrane platform that synergizes high-performance separation with environmental sustainability.

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 ：
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 ：
P-N-B organic flame retardant was synthesized using 4-formylphenylboronic acid, 4-aminophenylthiophenol, 9,10-dihydro-9-oxa-10-phos-phaphenanthrene-10-oxide (DOPO), and then introduced into the hydroxyl-terminated polybutadiene acrylonitrile (HTBN) molecular chain to successfully prepare a macromolecular flame retardant, which was used to prepare flame retardant waterborne polyurethane. The mechanical properties, thermal properties, and flame retardancy of waterborne polyurethane (FR-WPU) were studied using thermogravimetic analysis (TGA), limiting oxygen index (LOI), scanning electron microscope (SEM), cone calorimeter, and universal testing machine, respectively, and the flame retardant mechanism of macromolecular flame retardants was explored. An LOI value of 29.76% and a UL-94 V-0 rating could be realized when the APFBH conjugation is 7.5 wt%, showing a significant improvement of melt dripping behavior and flame retardancy. It indicated that the fire resistance of FR-WPU remarkably improved and displayed both gas and condensed phase mechanism. As the content of APBDH increased, the tensile strength and the elongation at break of FR-WPU increased firstly and then decreased.

Abstract ：
Photocatalysis is a promising technology for removing micropollutants in water. However, developing efficient and stable catalysts remains a challenge. In this work, a novel step-scheme (S-scheme) heterojunction of WO3/SnIn4S8 (WSI) was constructed through the combined process of in situ precipitation with hydrothermal synthesis to simultaneously realize photocatalytic degradation of bisphenol A(BPA) and reduction of Cr(VI) in contaminated water. Results showed that the WSI S-scheme heterojuction has a synergistic effect for the removal of BPA and Cr(VI). An optimum case of the WSI-12% heterojunction exhibited the highest photocatalytic efficiency in the degradation of BPA under visible light, which is ca. 2.5 and 3.8 times more than the pure WO(3 )and SIS, respectively. The enhanced photocatalytic activity is attributed to the formation of the WSI S-scheme heterojunctions which facilitate the spatial separation of charge carriers and preserve strong photoredox ability. Further, the S-scheme mechanism of enhanced photocatalysis was examined by the radical-trapping experiment and ESR, and superoxide and hydroxyl radicals were determined to be the major reactive oxygen species responsible for BPA degradation and Cr(VI) reduction by WSI. This work provides a novel strategy for tailoring high-performance S-scheme heterojunctions and shows the promising application in purifying wastewater with complex pollutants.
