Electrochemical, electrochromic behaviour and effects of supporting electrolyte on nano-thin film of poly (3,4-ethylenedioxy thiophene)

Electrochemical polymerization of 3,4-ethylenedioxy thiophene (EDOT) was prepared in p-toluene sulphonic acid, phosphate buffer and borax buffer on glassy carbon and ITO surface. Polymer film shows good electrochromic behaviour at oxidation and reduced potential condition.
