2 Outline Introduction Applications Conclusions
Theory and mechanism of electropolymerization Applications Recent development of electropolymerization Conclusions

3 Electropolymerization
Reynolds research Lab. The first electropolymerization experiment reported in 1968 by Dall’oxlio → Pyrrole in water medium The first determining event was the electro-polymerization in an organic medium reported in 1979 by Diaz → Pyrrole in MeCN

4 Mechanism of Electropolymerization
Rajesh*, Biomaterial, 2007, 28,

5 Mechanism of Electropolymerization
What’s Emonomer and Epolymer R. J. Waltman*, J. Bargon*, Can. J. Chem., 1986, 64, 76

6 R. J. Waltman*, J. Bargon*, Can. J. Chem., 1986, 64, 76

7 Group effect A. F. Diaz*, J. Electroanal.. Chem., 1981, 129 ,

8 Electrolyte effect Cyclic voltammogramms of [Pt]polypyrrole (20 nm) an CH3CN contaning various electrolyte salts Sweep rates 50 and 100 mV s-1
