Abstract

Porous and/or curved 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, production of long unbranched nanofibers, and the like.

Claims (3)

1. A method of producing a vapor absorbing fabric, the method comprising:

providing a porous activated carbon fabric substrate that comprises a plurality of apertures disposed therethrough, the substrate comprising an overall surface area that includes an interior wall surface area of the plurality of apertures; and

providing a plurality of nanocrystals attached to at least a portion of the overall surface area of the activated carbon fabric substrate, which nanocrystals absorb or decompose at least one non-organic gas, wherein the nanocrystals comprise ZnO, CuO, Cu 2 O, Al 2 O 3 , TiO 2 , MgO, FeO, Fe 2 O 3 , MnO 2 , Mn x O y , or Zn, thereby producing the vapor absorbing fabric.
