聚3-甲基噻吩和聚冠醚膜电极的研制与应用

Fabrication and Applications of Poly(3 Methylthiophene) and Poly(Crown Ether) Films Electrodes

以五员杂环或冠醚及其衍生物为聚合单体，以玻碳或铂为基体，用电沉积法制备了导电聚合物膜修饰电极。该修饰电极与铂电极、玻碳电极相比，具有灵敏度高、抗污染能力强、稳定性好的特点，并具有一定的广泛适用性，可用于各类电化学分析法，如伏安法、电位法。

Electroconducting polymer modified glassy carbon and platinum electrodes have been developed with five membered heterocycles or crown ethers and their derivatives as monomers by a electrodeposition method.The electrodes offer the distinct advantages of high sensitivity,strong antifouling ability and good stability over conventional non modified glassy carbon and platinum electrodes,and all of these advantages contribute to broadening their applications.They can be widely applied in electroanalytical techniques such as voltammetry,potentiometry and conductometric methods etc.
