Electronic properties of carbon nanotube/fabric composites
David S. Hecht,Liangbing Hu,George Gr?ner 한국물리학회 2007 Current Applied Physics Vol.7 No.1
Single walled carbon nanotube (SWNT)/fabric composite materials were manufactured using two simple manufacturing processes. Thetransfer technique. The composite retains high mechanical strength (governed by the fabric), and good electrical properties (determinedby the nanotubes). We measure the DC electrical conductivity of the composite fabric to be 5.33 S/cm for the sprayed tubes, 13.8 S/cmfor the incubated SWNTs, and 8 S/cm for the QLB transferred tubes; these values are limited not by the nanotube network, but by thesurface roughness of the fabric itself. Measurements of the conductivity up to 1 MHz reveal a transport process that proceeds along a ran-.C)andmechanicaldeformations.Theconductivityofthecompositedecreasesbylessthan10%whenbentaroundacylinder of1 cmdiameter.
