A METHOD OF FORMING A COMPOSITION AND THE COMPOSITION FORMED THEREFROM

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 thecomposition 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. 在一方面，一种制备组合物的方法，包括：形成包含聚合物和溶剂的溶剂混合物；将溶剂混合物与非溶剂沉淀以在原纤化聚合物基质中形成包含填料的组合物，其中该组合物是以颗粒的形式，并且溶剂和非溶剂中的至少之一包含填料；以及将组合物与溶剂和非溶剂分离以对组合物进行离析。在另一方面，一种多
