Abstract

The invention provides composite porous materials in which a second material is fused to and/or is in the pores and/or is fused directly to some of the pore walls of a porous first material. The invention also provides methods of filtering a fluid using these composite porous materials and methods of manufacturing the composite porous materials. Fig. is a scanning electron micrograph of a cross-section of a porous PVDF membrane cast onto a porous PE substrate.
