Novel bioderived cross-linked polyphosphazene microspheres decorated with FeCo-layered double hydroxide as an all-in-one intumescent flame retardant for epoxy resin

A green and facile strategy for preparing high-efficiency flame retardants is highly desirable given today's increasingly environmentally friendly requirements. In this study, novel bioderived cross-linked polyphosphazene microspheres (PHDTs) were synthesized through polycondensation with tannic acid and 4,4′-dihydroxybiphenyl as co-monomers and decorated by layered double hydroxide ([email protected]) to improve the flame retardancy of epoxy...
