Abstract
A semiconductive material which is formed by impregnating glass fibers or glass fabric with an organic material which is pyrolyzed in the substantial absence of oxygen and at a temperature which is above the pyrolysis temperature of the organic material, but below the boiling point or sublimation temperature of the organic material. By such pyrolysis, the organic compound is converted to substantially pure carbon deposited on the glass fibers which impart to the glass fibers semiconductive characteristics.
Claims27
A semiconductive material comprising glass fibers which are pyrolyzed in the substantial absence of oxygen in the presence of an effective amount of an organic compound to render said glass fibers semiconducting by forming carbon deposited glass fibers.
A process for producing a semiconductive material, comprising:
- (a) depositing an effective amount of an organic compound on glass fibers;
- (b) pyrolyzing the glass fibers and organic compound deposited thereon at a temperature of at least 600.degree. C. in the substantial absence of oxygen to form carbon deposited glass fibers.
