Abstract
Porous nanofiber bearing substrate materials are provided having enhanced surface area for a variety of applications including as electrical substrates, semipermeable membranes and barriers, structural lattices for tissue culturing and for composite materials, and the like.
Claims17
A bandage, comprising:
- a flexible porous substrate having a plurality of apertures disposed therethrough, the porous substrate having an overall surface that includes an interior wall surface of the apertures and an exterior surface of the substrate;
- and
- a plurality of nanofibers deposited upon or attached to at least a portion of the overall surface of the porous substrate, wherein at least a portion of the nanofibers are attached to or deposited upon the exterior surface of the substrate and at least a portion of the nanofibers are attached to the interior wall surface area of the plurality of apertures, whereby when the bandage is applied to a wound, the nanofibers attached to the exterior surface of the substrate provide adhesion to surface tissues adjacent to the wound or to an opposing side of the substrate.
