Temperature-dependence of the Conductivity in Conducting Polymer Composites

The temperature dependence of the electrical conductivity of a conducting polymer composite is reported from 77 to 450 K. The relationship between the temperature dependence of the conductivity and the structure of the composite is discussed. The low-temperature electrical resistivity of low-density polyethylene/polypyrrole composite was also investigated and a linear relationship between the resistivity and T--1/4 was found in the liquid-nitrogen temperature range
