Proton and Electron Conducting Polymer Composite Films Based on SBS Triblock Copolymer

Conducting polymer films were prepared by introducing ionic groups via chemical modification of one of the blocks of the polystyrene-block-polybutadiene-block-polystyrene (SBS) triblock copolymer and by adding different amount of metal salts into the modified block copolymer. The butadiene part of the copolymer was partially sulphonated to prepare the proton conducting film while the epoxidized form was used to fabricate electron conducting films with different inorganic salts. The products were characterized by Fourier Transform Infrared (FTIR) spectroscopy, Scanning Electron Microscopy (SEM) and potential as well as conductivity measurements.
