摘要：
A thin, uniform membrane comprising polymeric fibrils or a combination of fibrils and particles, wherein the fibrils have randomly convoluted cross-sections, and a process for making the membrane are disclosed. The membrane may be on the surface of a substrate as part of a composite sheet, or as a stand-alone structure.
