Abstract :
We present dielectric measurements as a function of temperature T and frequency ω/2π of a series of polypyrrole(PPy)/epoxy composites. In these systems fractal structures are formed by the conductive PPy. From the observed scaling of the dielectric function ɛ* (ω,T) with T and ω physical insight in both the structure of the percolating network and the fundamental building blocks is obtained. The results are compared with earlier presented image analysis data.
