Abstract

Free standing films of the emeraldine base form of polyaniline have
been oriented via the application of uniaxial stress. The films have
been elongated to a maximum of 650%. When doped with hydrochloric acid
such oriented films show conductivities up to 350 Scm-1, and maximal
electrical anisotropy of 24:1. Optical reflectivity experiments have
shown a metallic behaviour to the optical properties of these films
although the observed optical anisotropy is not as large as the
electrical anisotropy of the films. For the first time the intrinsic
physical properties are becoming manifest in polyaniline.
