Static and dynamic electrical breakdown in conducting filled-polymers

Lamaignère, L.; Carmona, F.; Sornette, D. - In: Physica A: Statistical Mechanics and its Applications 241 (1997) 1, pp. 328-333

The electrical resistance of a percolating medium made of a polymer filled with conductive particles may undergo a steep increase over a narrow temperature range above room temperature. A likely mechanism for the effect is the loss of interparticle contact inducing a weakening of the...

Nonlinear conduction in composites above percolation threshold — beyond the backbone

Bardhan, K.K. - In: Physica A: Statistical Mechanics and its Applications 241 (1997) 1, pp. 267-277

We review here the response of mainly conductor-insulator mixtures just above the percolation threshold (pc) under dc bias. I–V characteristics changes from being linear to nonlinear as the applied bias is increased. Closer a sample is to pc, greater is the nonlinearity. Analysis of nonlinear...
