摘要

The frequency dependence of the electrical conductivities of polymer composites with different MWCNT contents is considered. The composite tested was obtained by means of a roller mixer. It is shown that the AC conductivities has frequency-independent and frequency-dependent regions. The frequency-independent region was approximated to the DC conductivity. The frequency-dependent conductivity increases with frequency according to an approximate exponential power law that can be indicative of the hopping mechanism of conductivity.
