Abstract
Methods of making porous composite materials are provided. These methods involve providing a sintered porous first polymeric material, providing a solution containing a second polymeric material dissolved in a solvent, and, depositing the solution onto the sintered porous first polymeric material to form a precipitated porous second polymeric material wherein a portion of the second polymeric material is fused to the sintered, porous first polymeric material by at least one direct physical bond, and the second polymeric material is in at least some of the pores of the first polymeric material. In some methods, the first polymeric material and the second polymeric material are soluble in the same solvent.
