Abstract
The present invention provides a multi-layered interlaced membrane comprising at least one substrate layer including a plurality of first polymer-based microfibers; at least one nanofibrous layer including a plurality of second polymer-based nanofibers where each of the nanofibers has one or more nano-branches; at least one interlaced layer including a plurality of third polymer-based submicron fibers where each of the submicron fibers has one or more nano-branches and a plurality of fourth polymer-based nanofibers where each of the nanofibers has one or more nano-branches, wherein the third polymer-based submicron fibers are interlaced with the fourth polymer-based nanofibers; at least one submicron fibrous layer including a plurality of fifth polymer-based submicron fibers where each of the submicron fibers has one or more nano-branches. The nanofibrous layer is positioned onto the substrate layer; the interlaced layer is positioned onto the nanofibrous layer; the submicron fibrous layer is positioned onto the interlaced layer.
