Functionalization of layered double hydroxides by intumescent flame retardant: Preparation, characterization, and application in ethylene vinyl acetate copolymer

► LDHs were modified with compound PAHPA. ► EVA/PAHPA-LDHs nanocomposites were prepared by melt blending. ► PAHPA-LDHs improved the flame retardancy of the nanocomposites.
