摘要：

A positively-charged sol-gel silicate was simply prepared by hydrolyzed and co-polymmerized N-octadecyldimethyl[3-(trimethoxysilyl)propyl]ammonium chloride (C-18-TMS) and tetraethyloxysilane (TEOS). The permeation of the prepared silica film was investigated by cyclic voltammetry (CV). The film shows selectivity by charge exclusion, that is, favorably selective permeation of anionic redox probe and rejection of cationic one. Furthermore, the film shows a little higher relative response to inorganic anionic redox probe than its organic counterpart. (C) 2004 Elsevier B.V. All rights reserved.
