Preparation and Electrochemical Properties of Polyaniline Nanofiber Modified Graphite Foil
摘要
Abstract
Polyaniline nanofiber( Nano-PANI) modified graphite foil(GF) (Nano-PANI/GF) was prepared by electrochemical polymerization of aniline on GF electrode. The polymer on the modified electrode Nano-PANI/ GF was characterized by FTIR. The morphologies of the modified electrode were investigated by SEM. The Nano-PANI/GF electrode made through cyclic voltammetric scans in a solution of 0. 1 mol/L aniline and 1.0 mol/L HC1 showed good electroactivites in 0. 1 mol/L phosphate buffer solution(pH = 6.9). The electrocata-lytic properties of the modified electrode toward ascorbic acid oxidation were studied through cyclic voltamme-try and potentiometry. The current for ascorbic acid oxidation on the modified electrode at 0. 2 V showed linear response to the concentration of ascorbic acid in the range of 1. 7-2.0×103μmol/L. The detection limit of ascorbic acid on the modified electrode is 1. 7μmol/L( S/N = 3).关键词
