Polymer matrix composites comprising endothermic particles and methods of making the same

Abstract

A polymer matrix composite comprising a porous polymeric network; and a plurality of endothermic particles distributed within the polymeric network structure, wherein the endothermic particles are present in a range from 15 to 99 weight percent, based on the total weight of endothermic particles and the polymer (excluding any solvent); and wherein the polymer matrix composite has an endotherm of greater than 200 J/g; and methods for making the same. The polymer matrix composites are useful, for example, as a filler, thermal energy absorbers, and passive battery safety components.
