基于3,4-乙烯二氧噻吩和吡咯-3-甲酸的共聚物薄膜的制备、表征及电致变色性能
Preparation, Characterisation and Electrochromic Properties of Copolymer Films Based on 3,4-Ethylenedioxythiophene and Pyrrole-3-Carboxylic Acid
摘要
Abstract
Four new copolymers P (EDOT ∶ P3C)-1,P (EDOT ∶ P3C)-3,P (EDOT ∶ P3C)-5,P (EDOT ∶P3C)-10 were prepared via electrochemical co-polymerization using different molar ratios(1 ∶ 1,3∶ 1,5∶ 1,10∶1) of 3,4-ethylenedioxythiophene(EDOT) and pyrrole-3-carboxylic acid(P3C).The prepared four copolymers have good electrochromic properties,high electrochemical activity and good transmittance.Compared with poly (3,4-ethylenedioxythiophene) (PEDOT),the prepared copolymers have more abundant color change.P(EDOT∶ P3C)-1 has mainly four colors under different potentials,namely,dark red,pale brown,grey blue and blue.P(EDOT∶ P3C)-3 and P(EDOT∶ P3C)-5 possess the color change of purple,light purple and blue.P (EDOT∶ P3C)-10 can be dark purple,light purple and blue under different potentials.In addition,we also prepared a copolymer P(EDOT∶ P3C)-1-Ti based on EDOT,P3C and polyoxotitanate cluster [Ti7(OEt) 19O5(CoBr)].This film not only exhibits typical electrochromic properties but also has the ability of electric-catalytic oxidation of water.关键词
