Abstract :Polymerizations of pyrrole and thiophene on a platinum foil coated by polyethylene adipate insert ignore into journalissuearticles values(PEA); were carried out in acetonitrile by electrochemical methods. Different compositions of semi-conducting composite films of PEA/Polypyrroleinsert ignore into journalissuearticles values(PPy);, PEA/Polythiopheneinsert ignore into journalissuearticles values(PT); were prepared by the electrochemical polymerization of pyrrole and thiophene on PEA electrode. The polymerization was possible only for a certain thickness of the polyethylene adipateinsert ignore into journalissuearticles values(PEA); on the platinum. Conductivities of PEA/PPy, PEA/PT, films at different compositions were obtained. The films were examined by FTIR spectroscopy. The topography of surface films were analyzed by a scanning electron microscopeinsert ignore into journalissuearticles values(SEM);. The conductivity behaviour of insert ignore into journalissuearticles values(PEA/PPy);, insert ignore into journalissuearticles values(PEA/PT); films at different compositions when exposed to Ar, N2, C3H8 and H2 gases indicated that these films cannot be used as gas sensors.
