Abstract
A polymer matrix composite comprising a porous polymeric network; and a plurality of dielectric particles distributed within the polymeric network structure; wherein the dielectric particles are present in a range from 5 to 98 weight percent, based on the total weight of the dielectric particles and the polymer (excluding the solvent); and wherein the polymer matrix composite has a dielectric constant in a range from 1.05 to 80; and methods for making the same. Polymer matrix composites comprising dielectric particles are useful, for example, as electric field insulators.
