【摘要】采用POAP为导电聚合物,制得了POAP修饰的铂电极,并研究了在POAP修饰铂电极上银的电沉积。同时用循环伏安,XPS和SES对膜进行了表征。研究发现pH≤3时,铂电极上可形成一层导电聚合物(POAP)膜且表现出电活性。该电极具有良好的稳定性和重现性,对银离子是一种敏感型电极。更多还原

【Abstract】 POAP modified platinum electrode was prepared using POAP as conducting polymer,and electro-deposition of silver on POAP modified platinum electrode was studied.The characteristics of film were studied using cyclic volt-ampere,XPS and SES.The research results showed that the POAP films formed on platinum electrode displayed conductibility,stability and repeatability at pH≤3,indicating that it was a Ag+-sensitive type electrode.更多还原
