Summary: In this study, bioinspired web-liked multiphase composites were successfully constructed using boron-modified polysilazane polymer. The composites consisted of long TiB nanowires as 'web' and hybrid TiC and Ti3Si particles as 'nodes'. The enhanced strength of these composites was attributed to the synergistic load transfer of the hybrid reinforcements. This study provides a promising design approach for developing high-performance composites with high reinforcement content, utilizing polymer instead of traditional ceramic powder.

Summary: In this study, flexible and rigid polyurethane/copper composites were prepared via a simple solution casting process. The dispersion and chemical bonding of the filler were investigated, and the thermal properties and mechanical properties of the composites were analyzed. The results showed that the thermal conductivity of the composites was significantly improved compared to the pure polyurethane, and the mechanical properties were also enhanced. The study suggests that copper microparticles can serve as an active filler in both flexible and rigid polyurethane matrices.

Summary: In order to meet the diversified requirements for polymer-based composites in modern electronic devices and electrical systems, the simultaneous enhancement of thermal-electrical-mechanical properties is a great challenge. The gradient structured composites, designed by adjusting the distribution of temperature, electric and stress fields in polyethylene (PE) based composites with different Al2O3 contents, demonstrated superior through-plane thermal conductivity, high breakdown strength, and good tensile strength. Finite element simulation provided evidence for the action mechanism on gradient structure regulating temperature and electric field. The strategy of constructing gradient structure provides a feasible route to meet the comprehensive performance requirements of PE based composites in massive manufacture scenario for practical insulation applications.

Summary: TiAl alloys have potential as high-temperature materials due to their lightweight and high-strength properties, but face challenges with brittleness and microstructure stability. The use of composite materials, specifically carbides, can enhance the mechanical properties of TiAl matrix composites. The addition of carbon can improve tensile properties and strength, while also reducing creep rates in TiAl alloys.

Summary: In this study, core-shell structured polydopamine functionalized silicon carbide whiskers were successfully synthesized to improve the dielectric properties of the composites. The presence of PDA effectively suppressed the dielectric loss, and the thicker PDA layer contributed to enhancing dielectric breakdown strength and reducing AC conductivity. This simple coated PDA shell strategy could be extended to develop high performance dielectric polymer composites with other inorganic fillers.

Summary: A noble metal-free high-activity ORR catalyst F-N/FeNC with a 3D interconnected porous structure and high conductivity is successfully prepared by doping heteroatoms F and N on precursor Fe-zeolitic imidazolate framework (ZIF)-8, improving the activity of Fe-ZIF-8-derived porous carbon materials. The synergistic effect of C-F ionic bonds, pyridinic-N, pyrrolic-N, graphitic-N, FeNx sites, and C-F semi-ionic bonds in F-N/FeNC can improve its ORR activity. F-N/FeNC has excellent specific surface area, ultra-high electrical conductivity, and extremely high ORR mass transfer efficiency.

Summary: Co-N-C catalysts with hollow core-shell structures and abundant carbon nanotubes (CNTs) have been prepared and their performance in oxygen reduction reaction (ORR) has been explored. The prepared electrocatalyst Co/NHCNT-160 exhibits good catalytic activity and a nearly four-electron reaction path. Its ORR performance exceeds that of commercially available Pt/C catalyst and most non-precious metal catalysts. The excellent catalytic performance of Co/NHCNT-160 is attributed to its unique structure, the abundance of CNTs, high degree of graphitization, graded pores, and functionalized Co-Nx active sites with a highly dispersed carbon backbone. This catalyst preparation strategy will provide insights for the development of other ZIF-based ORR catalysts for energy storage and electrochemical devices.
