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

3 3 Electropolymerization 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 Reynolds research Lab.
