Thermally processible polyaniline (PANT) 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 Ω-cm. PANI blends with the crystalline polymers clearly showed both the positive temperature coefficient (PTC) and the negative temperature coefficient (NTC).
