水溶液中以无机阴离子为掺杂剂动电位法合成聚吡咯

以HCl、KCl、NaCl、NH4Cl、NaNO3、Na2SO4和Na3PO4为掺杂剂动电位法快速合成聚吡咯,聚吡咯的循环伏安特性在0.1M磷酸盐缓冲液中表征.结果表明,掺杂剂阳离子不同,对聚吡咯膜的性质影响不大,而对于化合价为单价、二价及三价的不同阴离子掺杂聚吡咯的性质有明显不同.

Potentialdynamic Polymerization of Polypyrrole Films with Inorganic Dopants in Aqueous Solution

Potentialdynamic polymerization of polypyrrole films were synthesized with the dopants of HCl,KCl,NaCl,NH4Cl,NaNO3,Na2SO4 and Na3PO4.The cyclic voltammetry was carried out in 0.1M phosphate buffer to characterize the prepared ppy films electrochemically.The results indicate that the canions of the dopants have little effect on properties of the ppy films,but the properties of ppy films doped with different anions of monovalence,divalence or trivalence differs obviously in electrolyte solutions.
