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.
Claims1
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, Cu2O, Al2O3, TiO2, MgO, FeO, Fe2O3, MnO2, MnxOy, or Zn, thereby producing the vapor absorbing fabric.
