Abstract

Proton relaxation times T-1 and DC conductivity have been measured on
unstretched and stretched polyaniline films, in the dried and the
hydrated states. It is shown that polaron motion is highly anisotropic
at the chain scale and that stretching increases interchain hoppings.
On stretched films, hydration induces an increase of the conductivity
but a decrease of its anisotropy. The data are accounted for in a
simple model which links the macroscopic transport properties to the
microscopic ones.
