Abstract

Polyvinyl alcohol–polypyrrole–multiwall carbon nanotube composite polymer films have been synthesized by a chemical oxidative polymerization technique. Dielectric properties have been measured in the frequency range from 20 Hz to 1 MHz and in the temperature range 77 ⩽ T ⩽ 300 K. Electric modulus vector analysis gives the presence of dielectric relaxation peaks for different composites from which the activation energies have been calculated.
