Electrically conducting PVDF/PAN/poly(pyrrole) composite r s have teen prepared by polymerizing pyrrole vapor in PVDF/PAN composite films impregnated with ferric chloride as an oxidant. As polymerization of pyrrole proceeds, poly(pyrrole) has been observed as uniform continuous phase in PVDF/PAN composites. The electrical conductivities of composite films reach in the range of 10^-3∼10^-2S/cm and the stability of conductivity to the ambient air exposure is excellent. The formation of poll (pyrrole) in PVDF/PAN composites has induced increasing disorder in host composite matrix and increased the tensile elongation.
