Abstract
The electrochemical copolymerization of aniline ANI with 1amino910anthraquinone 1AAQ was carried out in 4 M sulfuric acid by potential cycling in the potential range of −01 V to 13 V vs SCE Copolymer films were grown from different feed ratios of ANI and 1AAQ 0208 0406 0505 0604 0802 on a glassy carbon electrode GCE Studies on the effect of scan rate on the conductivity of the copolymer film confirmed the formation of a stable conducting copolymer film The FTIR spectrum recorded for the copolymer film provides concrete evidence of copolymer formation since it indicates the presence of quinone units in the copolymer backbone XRD data particle size 47 nm and SEM grain size 100 nm micrographs provide a clear picture of the nanosized polymeric particles formed It is envisaged that the newly reported copolymer could be a useful material for performing the catalytic reduction of oxygen in an acidic medium—a useful process for fuel cell applicationsOne of the authors SPPalaniappan would like to thank CSIR New Delhi for providing a Senior Research Fellowship vide CSIR letter no 9/688011/9EMRI dt 23042009 and P Manisankar would like to place on record his sincere thanks to the University Grants Commission New Delhi India for the financial support extended to the Department of Industrial Chemistry through the SAP scheme
