Abstract

The electrical conductivity of two isotropic 50% CSA doped polyaniline
films were measured to be (300+/-30) S/cm. Four samples were cut from
one isotropic film and drawn to various extensions at 150C. An
additional four samples were cut from the other film and similarly
drawn at 155C. The conductivity's parallel (sigma(parallel to)) and
perpendicular (sigma(perpendicular to)) to the draw direction were then
measured using a four-in-line probe. The most highly drawn film had an
extension of 120% and gave sigma(parallel to) of(967+/-30) S/cm and
sigma(perpendicular to) of (100+/-20) S/cm, an anisotropy of 9.67, the
different draw temperatures had no effect on the conductivity measured.
The conductivity enhancement is attributed to orientation of both the
crystal and amorphous phases.
