Abstract:
1. A method for forming a nanofibrous non-woven sheet, the method comprising: synthesizing a volume of free-flowing nanotubes from a carbon source and a plurality of catalyst particles; depositing the volume of free-flowing nanotubes continually onto a moving surface; transporting the volume of nanotubes continually deposited onto the moving surface away from a point of deposition; applying pressure onto the plurality of nanotubes against the surface, so as to compact the nanotubes into a non-woven sheet of intermingled nanotubes; directing the non-woven sheet toward an area independent of the moving surface for collection; putting a material onto one side of the non-woven sheet to prevent the non-woven sheet from bonding to itself; and collecting the non-woven sheet from the moving surface by winding the sheet about an axis substantially transverse to a direction of movement of the sheet.
