Abstract

We report measurements of the conductivity, σ, of carbon-PVC composite as a function of the carbon weight %, ω, in the composite. Below some critical carbon content, ω_c, the conductivity drops sharply while above this ω_c we find a power-low behavior σ ∝ (ω - ω_c)^t. The best fits of the data with this power-law show that 1.5 <t<2.1 and correspondingly 9.5>ω_c>9.0. This is in good agreement with the predicted universal value, t = 1.7, and the experimental value obtained for a system containing sphere-like conducting particles, t = 1.9 ± 0.2.
