FREE STANDING FILM OF POLYANILINE

Received Date: 10 April 1990

A free standing film of polyaniline as large as 18 cm×18cm×0.002 cm can be obtained by evaporation of a solution of the chemically synthesized base in NMP. Its structure was examined by the elemental analysis, IR, U.V.-visible spectra, XPS, DSC, SEM and X-ray scattering and its conducting behavior as well as electrochemical properties were studied. Results show that the composition, structure of main chain, physical properties of the free standing film of polyanilme is similar to that of the powder. However,some differences in its electronic structure,conductivity at room temperature and potential of redox couple between the free standing film and powder are observed,which may be due to cross-linking of the film of polyaniline.
