Carbon with a metallic reflection was prepared from polyaniline (PANI) vapor deposited on the inner quartz wall of a furnace.Electron probe microanalyzer analysis proved that the resultant contained carbon, Electrotherapy and Sonic Therapy - Electrotherapy Electrodes oxygen, nitrogen, and sulfur atoms.A Dysonian line shape with paramagnetic properties was observed for the resulting carbon from PANI in the electron IP/Network spin-resonance spectroscopy measurement.The resistance vs.
temperature curve of the carbon indicated semiconductor-insulator properties in a low-temperature range.Electrical conduction in the carbon was carried out with 3D variable range hopping.
