摘要
The incorporation of a Keggin-type heteropolyanion, the phosphotungstate ([PW12O40](3-)), into polypyrrole has been achieved during the electrochemical preparation of the polymer films in aqueous solution. The redox behaviour of these modified electrodes is described by using cyclic voltammetry (CV) and electrochemical quartz crystal microbalance (EQCM). The data allowed to estimate the doping level that indicates the extent of the heteropolyanion insertion. It is found that the polymer films, in aqueous solution, exhibit sensibility to cations, namely to Na+. (C) 2002 Elsevier Science Ltd. All rights reserved.
