The conductive properties of carbon black filled polymers have already found many qualitative applications while quantitative ones remain infrequent because of the number of unexpected parameters which influence the conductance of samples of the material. We have tried to connect the anomalous electrical behaviour of such materials with three particular phenomena which influence d-c conduction: -Percolation, which is a process expected to occur in mixtures of conducting and insulating solids. -Volumic polarization and ionic heterocharge near the electrodes which supply a new explanation for the variable contact resistance. -Filamentary conduction and localized thermal effects which produce under some conditions, regions of negative resistance in the current-voltage characteristics of samples. Possible electrical applications for filled polymers are deduced from this analysis. |
