Abstract
The electrochemical behavior of glassy carbon and PVDF synthesis graphite materials with compact surface have been characterized by impedance spectroscopy. The Faraday-impedance both carbon materials were depended highly on polarization and the difference of electrochemical behavior accord to structure of surface between glassy carbon and synthesis graphite was represented, in these evaluated equivalent circuits, PVDF synthesis graphite was indicated with form that is added resistance and capacitance by the hydrophobic binder to glassy carbon equivalent circuit.
