Abstract

Some POLYPYRROLE free standing films or MEMBRANES doped with different electrolytes (aromatic sulphonated) were prepared from aqueous monomer solutions in order to investigate the effect of THERMAL TREATMENT on their ELECTRICAL CONDUCTIVITY. It was found that the nature of counterion has the most important effect in determining of the ELECTRICAL CONDUCTIVITY and stability of conductivity when polymer exposed to high temperatures. However, mild heating can improve conductivity of POLYPYRROLE conducting polymers. In order to carry out thermal studies on conductivity and measure the thermal stability of the ppy film, a variety of anions were tried. It was found that POLYPYRROLE doped with aromatic sulphonates (mainly benzene or naphthalene sulphonates) as COUNTERIONS produce flexible, and smooth films that can be readily detached from working electrode as membrane with good mechanical properties. Other COUNTERIONS such as inorganics (e.g. Cl-, SO42-), aliphatic surfactants (e.g., DS), and polymeric (PVS) produced films that is either impossible to remove from working electrode or give brittle, and rough films.
