Electrospinning fine polymer nanofibers onto a microporous membrane involves inductively charging a solution of high molecular weight polymers to approximately 10,000 volts, emitting fine jets of charged fiber from the solution surface, and collecting the fiber onto a grounded or oppositely charged substrate, such as a fabric covered electrode, for direct deposition. The electrospun layer possesses the consistency of conventional microporous membranes. Filtration capabilities include submicron particles. Average fiber size ranges from 100-500 nanometers, imparting high surface area characteristics to the membrane and enabling the immobilization of absorptive and reactive materials within the fibrous structure. An enzyme that degrades toxic organophosphorus compounds covalently attaches to cotton surfaced nonwoven fabrics to functionalize the fabric for use as a decontaminating surface. 19 refs.
