“…The preparation, characterization and application of electrochemically active, electronically conjugated polymeric systems are in the foreground of research activities in electrochemistry [Heinze et al, 2010]. Among the conducting polymers, polypyrrole has attracted a lot more interests [Jang & Oh, 2004;Zhang et al, 2006;Chang et al, 2009]. This polymer is easy to synthesize both chemically and electrochemically, exhibiting good electrical conductivity and relatively good stability under ambient conditions, but lacking good electroactivity and redoxability.…”
