ABSTRACT:
A composite fiber is made of non-organic particulates bound to an organic polymer in fiber form. Many non-organic substances are serviceable and valve metal oxides are highly suitable. The organic polymer fiber is advantageously derived from fluorine-containing polymer. The composite fibers can serve as a filter, for instance as a filter-packing material for column chromatography, or can be suitable for separations, e.g., battery separations. The fiber may be compressed, or compressed and sintered, and thereby be useful as bearings or gaskets.
