4、manufacture conductive silicone polyurethane (PPy/HESO). The eects of dierent preparative conditions including feeding ratios, feeding sequences and reaction conditions were investigated. The results show that the optimum preparative conditions arepyrrole to HESO mass ratio 12.5:100, ferric chloride

5、 and anthraquinone 2sulfonate(AQS) to pyrrole molar ratio of 2.2 : 1.2 : 1, feeding sequence: HESOPyrroleAQSFeCl3, reaction temperature 0 , pH=3 of the reaction solution. Eect of the Si and polypyrrole on electrochemical properties has a concertedness. It is more conducive to PPy/HESO, and forming a
