Mechanical properties of conducting H-type polysiloxane-polypyrrole graft copolymers and polytetrahydrofuran-polypyrrole block copolymers

The mechanical properties of block copolymers of polypyrrole and pyrrolyl-ended azobis-polytetrahydrofuran (TPPy) and graft copolymers of pyrrolyl-ended H-type polydimethylsiloxane (SPPy) were investigated and compared with those of polypyrrole (PPy), Conducting films were prepared electrochemically at a constant potential and doped with p-toluene sulfonate.
