Summary

The beta silicon carbide whiskers, as prepared by the “Los Alamos Process,” have been found to have conductivities as high as 300 (Ωcm)−1. Random, uniform incorporation of these whiskers in two high temperature polymers (polybenzimidazole and polypyrrone) in 10 and 20 wt% concentrations generated films with conductivities as high as 1 × 10−9 (Ωcm) and 1 × 10−5 (Ωcm)−1 respectively. The polymers without the whiskers had conductivities in the 10−10 to 10−17 (Ωcm)−1 range.
