Abstract:

 

Copolymer films of N-methylpyrrole (N-MPy) and  N-methylcarbazole (N-MCz) were synthesized electrochemically onto  single carbon fiber microelectrodes (CFMEs).  Deposition conditions on  the carbon fiber, influence of the monomer concentrations on the  copolymerization of P[N-methylpyrrole-co-N-methylcarbazole]  P[N-MPy-co-N-MCz], and the electrochemistry of the resulting  homopolymer and copolymers were studied using cyclic voltammetry,  FTIR-ATR, in-situ spectroelectrochemistry, a UV-vis spectrophotometer,  and a 4-point probe conductometer.  The effects of current density,  supporting electrolyte type, temperature, and monomer concentrations  on the formation of the film were studied.  Redox parameters and  stability of charged films were obtained by cyclic voltammetry.  The  most stable copolymer was obtained in lithium perchlorate-acetonitrile  electrolytic solution (LiClO4/ ACN).
