  1. Electropolymerization Advisor : Professor Guey-ShengLiou Reporter: Ming-Chi Tsai Date : 2014/01/03

  2. Outline • Introduction • 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, 791-805

  5. Mechanism of Electropolymerization What’s Emonomerand 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 , 115-132

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