Abstract

See full text

In an aspect, a method of making a composition, comprising forming a solvent mixture comprising a polymer and a solvent; precipitating the solvent mixture with a non-solvent to form the composition comprising the filler in a fibrillated polymer matrix, wherein the composition is in the form of a particulate and at least one of the solvent and the non-solvent comprises a filler; and separating the composition from the solvent and the non-solvent to isolate the composition. In another aspect, a porous material wherein the filler particles are mechanically bonded together by the polymer and wherein the polymer is present as filaments adhering to and connecting the filler particles across interstitial spaces between the filler particles. In another aspect, a precipitated polymer solution produced by a phase inversion where the majority of the liquids can be mechanically removed.
