Abstract:
1. A method for making a porous material, said method comprising the steps of: (a) melt-blending two or more non-miscible polymers to obtain a co-continuous melt; (b) solidifying the melt of step (a) to obtain a solid mass; (c) selectively extracting at least one of the polymers from said solid mass with a solvent, thereby creating an essentially continuous pore network within said solid mass, said pore network having an internal surface; (d) depositing one or more precursor layers on the internal surface of said pore network, wherein each of said one or more precursor layer is a polyelectrolyte layer; (e) replicating the internal surface of the pore network within said solid mass by coating said internal surface with successive material layers; and (f) selectively extracting said solid mass with a second solvent without extracting said layers, thereby producing a porous material.
