Abstract

A novel composition for high reliability photoreceptor grounding devices is disclosed. A progenitor composition comprises: a multi-filament, continuous strand, polymeric thermoplastic yarn 1; a thermally stable, carbon fiber filler 2 blended with the thermoplastic yarn in center region 3; and carbon fiber strands 4 in a matrix resin surround 5 encasing center region 3. The progenitor composition is heated to about 410 to 600°C whereupon the thermoplastic yarn and matrix resin decompose and vaporize at about the same rate resulting in a residue comprised of brush-like filament ends comprised of only unbound carbon fibers having the desired conductivity properties suitable for a grounding device.
