本文以不同尺寸的聚苯乙烯乳胶球为模板，在高氯酸锂(LiClO4)水溶液中的神经探针微电极上电化学沉积了导电聚合物聚(3，4-乙二氧基噻吩基)(PEDOT)和聚吡咯(PPy)微孔膜。这些样品的扫描电子显微镜显示了由具有相互连接的通道的空洞组成的三维微孔结构。研究了导电聚合物沉积量对微孔涂层形貌的影响。薄膜的表面形貌随聚苯胶球的粒径和涂层厚度的不同而不同。在电极上电沉积的不同孔径的微孔导电聚合物薄膜具有较高的孔径规律性。(C)2004爱思唯尔B.V.保留所有权利。
In this paper, microporous films of the conducting polymer poly (3,4-ethylenedioxythiophene) (PEDOT) and polypyrrole (PPy) were electrochemically deposited on the microelectrodes of neural probes from aqueous solution of lithium Perchlorate (LiClO4) using different sized polystyrene latex spheres as templates. Scanning electron microscopy of these samples revealed a three-dimensionally microporous structure consisting of voids with interconnected channels. The influence of the amount of deposited conducting polymer on the morphology of the rnicroporous coatings has been extensively studied. The surface morphology of the films was found to vary with the particle size of polystyrene latex spheres and coating thickness. The microporous conducting polymer films with different pore sizes electrodeposited on the electrode sites have high regularity in pore size. (C) 2004 Elsevier B.V. All rights reserved.
