“Anion-chromic” interactions of emeraldine base with hydroxide and halide anions in the solid polymer matrix
A behavior of polyaniline (PANI) composites with common polymers under different
conditions is often a result of a synergetic combination of properties of their components. In
this work we consider specificity of such a combination in terms of both hydrogen bonding of
PANI with a matrix polymer poly (ethylene terephthalate)(PET) and its influence on
interactions of the composite PANI–HCl/PET films or dedoped PANI/PET films with alkaline
and alkali metal halide aqueous solutions. In particular, it is found that PANI in emeraldine …
