Abstract
The polyaniline(PANI)-poly(vinyl alcoho1)(PVA) composite film doped with HC1 was prepared with PVA as matrix. Effects of PVA content, film drying temperature on properties of PANI-PVA composite film were studied. Tensile strength, elasticity, conductivity and thermal stability of PVA, HC1-PANI or PANI-PVA were compared. Tensile strength and elasticity of PVA film were the largest, its conductivity was the least. The conductivity of PANI-PVA was the largest, tensile strength and elasticity of PANI-PVA are bigger than those of HC1-PANI. The order of their thermal stability is PVA> HC1-PANI > PANI-PVA before 260°C, the order of their thermal stability is HC1-PANI>PANI-PVA> PVA after 260°C.
