Abstract
The electrical conductivity of polymeric materials containing conductive particles shows a typical percolation behavior. Besides this effect adding the particles to a polymer matrix affects the rheological properties considerably. In the literature one can find some studies relating the electrical percolation to a comparable change of rheological quantities. The term "rheological percolation" is introduced; however, its definition is not consistent in the literature. In this contribution some literature data obtained from dynamic-mechanical measurements are discussed and confronted with own data from oscillatory and creep-recovery measurements. From a critical evaluation of the data it follows that rheological properties change continuously with the filler content in the range of the electrical percolation threshold. A simple model is proposed to explain the differences between the electrical and rheological behavior of polymer composites.
