Abstract

Uniaxial stretching of polypyrrole (PPy) cast film significantly improved the electrical conductivity and break strength of the film in the stretching direction. The electrostatic effect of nitrogen atoms in pyrrole rings was also increased from 44% to 56% by stretching without change in the doping level. These phenomena indicate that stretching can induce more extended conformation of PPy molecules in the cast film.
