Temperature dependence of the electrical conductivity of thermoplastic polymer/polyaniline blend
Thermally processible polyaniline (PANI) was chemically synthesized by one-step polymerization and blended with various thermoplastic polymers, leading to the blends with the specific volume resistivities ranging from 10(2) to 10(4) Omega-cm. PANI blends with the crystalline polymers clearly showed both the positive temperature coefficient (PTC) and the negative temperature coefficient (NTC).
