| Abstract: | The electrochemical behavior of PPV/PEO blend with different dopants wasinvestigated by cyclic voltammetry. The p-doping process is electrochemically quasi-reversiblewhile the n-doping is irreversible. The band gap of the blend obtained by the cyclic voltammetry is2.45 eV, which is the same with that of pure PPV. |
