Abstract

We report the preparation and properties of ultra-thin films of
polyaniline formed by spinning. The polyaniline, dissolved in
N-methyl-2-pyrrolidinone, was found to behave as a non-Newtonian fluid.
However, high quality films could be produced under appropriate
conditions. From these spun films of emeraldine base, we have
calculated the absorption coefficient of both the benzenoid pi-pi*
transition observed at 320nm and the quinoid ring absorption seen at
610nm, which leads to self-trapped exciton formation.
