Conducting Polymer Composite Films Based on Triblock Copolymer. An insight into the preparation, characterization and uses

      Аннотация: The preparation of conducting polymer is an emerging and interesting field of polymer science.It has many useful applications in electronics, industries and electrical devices. In this work, the insulating polystyrene-block-polybutadiene-block-polystyrene (SBS) triblock copolymer was epoxidised by performic acid followed by blending with various metal salts which leads to the formation of electron conducting polymer films. In another set of experiments, the sulfonated ionomer was prepared from the epoxidised SBS block copolymer followed by ring opening reaction with an aqueous solution of sodium bisulphate. The products were characterized by FTIR spectroscopy, thermogravimetric analysis and scanning electron microscopy. The sulfonated ionomers behaves as proton conducting membranes due to the presence of SO3-Na+ groups on polymer backbone. This book will be useful for the researcher working in the field of block copolymer specially on conducting polymer.
