Carbon fibers grown by pyrolysis of natural gas were heat-treated at temperatures ranging from 1400 to 3OOO"C, and characterized by X-ray diffraction. Their electrical resistivity is reported for temperatures between 10 and 370 K, and explained for heat treatment above 2200Β°C using a simple graphiti
The changes which occur in the electrical conductivity of Saran carbon rods with the adsorption of both polar and non-polar molecules have been measured. No relationship between the polarity of the adsorbed molecule and the electrical conductivity of the adsorbent was found. An attempt has been made
