【Abstract】 The voltammetric properties of polyaniline on ultramicroelectrode in HCl media and the dependence of the peak current (i p) a on the polymerization charge(Q p) and the sweep rate are discussed. When the value of Q p is relatively small, the modified electrode behaves as a thin film coated electrode, while Q p is large, the peak current (i p) a is controlled by diffusion.更多还原
