摘要：

We investigated electropolymerization of polypyrrole into porous silicon template. We used three types of porous silicon templates, i.e., porous silicon with ordered macro pores, medium-sized pores and meso pores. Polypyrrole was electropolymerized from pore bottoms to pore tops in all the porous silicon templates. After removal of the templates we obtained rod-shaped polypyrrole arrays. Changing the porous silicon templates easily controlled the size of the rod-shaped polypyrrole. We also used dendritic medium-sized pores for template, and then polypyrrole rod having a roughened surface was obtained. Here we demonstrated that the size and the surface morphology of polypyrrole rod were easily tuned using porous silicon. (C) 2007 Elsevier B.V. All rights reserved.
