Nonlinear V-I characteristics of particulate composite prepared from dispersion of silicon carbide in a siloxane elastomer have been measured as a function of ller concentration up to the maximum allowable of about 32 vol.%. Two critical concentrations (percolation thresholds) are obtained at volume fractions of about 17 and 24 vol.% for low and high electric elds. These values are consistent with the critical concentrations predicted by the theory: 14 and 31 vol.% respectively and may come from edge and face contacts between SiC semi-conducting particles.

“…Fillers known to transfer their non-linear electric properties to the matrix of a composite mainly consist of ZnO microvaristors and/or other metallic oxides, [12][13][14][15][16][17][18][19][20] doped silicon carbide [21][22][23][24][25][26] or carbonaceous particles [27][28][29][30][31][32]. Among carbon fillers, nano-sheets have driven attention because nonlinear composites may be obtained at a low filling ratio (< 5 vol.%).…”

In the design of medium and low voltage equipment such as cable accessories, generator, motor end windings or bushings, issues with electrical field enhancement occur at interfaces between insulators and conductors, resulting in accelerated material ageing. The purpose of this paper is to present a novel dielectric composite material which has the properties to mitigate this local amplification. It is a functional dielectric which resistivity decreases by several orders with electric field from 10 14 to 10 9 Ωm up to 1 kVmm -1 while the dielectric constant decreases from 15 to 12 in the 10 -2 -10 6 Hz range. This novel material is made with graphite nanoplatelets.It may be used as a resistive or capacitive field grading material in electrical applications.
