摘要
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.
