Summary: Polyphosphazenes (PPNs) are organic-inorganic hybrid polymeric skeletal materials fabricated via precipitation or condensation polymerization and self-assembly approaches. Auto-doping feature of PPN materials allows for the formation of binary-, ternary-, and quaternary-doped carbon frameworks and graphitic carbon nitride (g-C3N4), providing a good range of surface areas and active sites for applications in solid-state batteries and supercapacitors. Structural irregularities and imperfections in PPN materials offer opportunities for water splitting reactions with lower half-wave potential compared to conventional electrocatalysts.

Summary: Although dielectric elastomer (DE) with substantial actuated strain (AS) has been studied for 20 years, its scientific understanding remains unclear. Contrary to the most accepted theory, experimental results show no relationship between theoretical AS and actual AS, leading to the proposal of a new cross-scale model for explaining the AS of DE.

Summary: Diels-Alder reactions are commonly used in Covalent Adaptable Networks (CANs) for making recyclable crosslinked materials. In this study, novel thermally switchable polymers were prepared, capable of transitioning from thermo-reversibly self-healing hybrid polymers to irreversibly highly crosslinked networks with outstanding flame retardancy. The convenient synthesis and flexible structure design of phosphazene provide new opportunities for CANs with tunable properties.

Summary: The study demonstrates the effective use of a multi-heteroatoms doping approach to synthesize mesoporous carbon materials with ultrahigh surface area. By tuning the silica dosage and carbonization temperature, the surface area and heteroatoms doping content of the synthesized carbons can be tailored. The tetra-atoms-doped mesoporous carbon exhibits ultrahigh surface area and enriched heteroatoms content, contributing to enhanced capacitive performance.

Summary: In this study, a cyclophosphazene derivative was successfully synthesized and used as a curing agent for epoxy resins, resulting in high-efficiency flame retardancy. The synthesized thermosets exhibited excellent flame retardant properties, thermal stability, and improved carbonization ability at elevated temperatures. Additionally, the release of combustible gases during the pyrolysis process was effectively suppressed by the incorporation of the cyclophosphazene derivative. The nonflammable halogen-free epoxy resin developed in this study has potential applications in the electric and electronic fields for environment protection and human health.

Summary: We reported a study on the preparation of bimetallic Ag-Cu nanoparticles impregnated on PZS poly(cyclotriphosphazene-co-4,4'-sulfonyldiphenol) nanotubes via a facile and efficient reduction method. The bimetallic NPs exhibited excellent dispersity, ultrasmall size, and were well-anchored on the surface of PZS nanotubes. The optimized Ag-Cu NPs showed remarkably high catalytic activity and outperformed their monometallic counterparts, laying the foundation for utilizing polyphosphazene polymer as a substrate material for highly effective bimetallic catalysts.

Summary: The synthesis of heteroatoms doped inorganic nanocrystal-carbon composites (INCCs) with homogeneous distribution of metal (alpha-Fe2O3) and non-metals (N, P, O) was achieved through a facile two-step route using hydrogel formed by treating hexachlorocyclotriphosphazene (HCCP) and 3, 4, 5-trihydroxy benzoic acid (Gallic acid). Four different samples (INCC-0.5%, INCC-1.0%, INCC-1.5%, and INCC-2.0%) were fabricated, showing uniform distribution of N, P, O, and alpha-Fe2O3 in the carbon architecture. INCC-1.5% exhibited superior catalytic performance in water oxidation catalysis (WOC), with higher methanol tolerance and stability compared to RuO2, attributed to the homogeneous distribution of alpha-Fe2O3 promoting initial O-2 adsorption and higher surface area with hierarchical pore size distribution facilitating ion transportation and mass-flux.
