Abstract

Free standing films of polyaniline in its emeraldine base form have
been cast from N-methyl-2-pyrrolidone solution. These films have been
characterised via FTIR and solid state C-13 NMR to unambiguously reveal
the chain structure of the emeraldine. The optical spectrum of the
films in both the base and salt forms has been measured. Further,
these free standing films have been oriented using uniaxial stress.
These aligned films have shown conductivities which range up to 350
Scm-1, two orders of magnitude higher than those previously reported
for polyaniline. For the first time we have been able to probe the
intrinsic physics of polyaniline.
