摘要：聚(3,4-乙撑二氧噻吩)（PEDOT）作为一种经典的导电聚合物（CPs）在电致变色领域具有广阔的应用市场。目前常规技术化学氧化法制备PEDOT及其衍生物（PEDOTs）虽然廉价快速，但所得聚合物容易呈粉末状，且这些粉末状聚合物在常见溶剂中溶解性差，进一步加工无法得到高质量薄膜。通过气相聚合（VPP）技术可以制备部分高质量的PEDOTs薄膜，但是这一技术局限于可以汽化的有机小分子。为此，本文设计了一种3,4-乙撑二氧噻吩（EDOT）的衍生物BT-4EDOT，借鉴VPP技术，将单体汽化过程用单体溶液喷涂方式代替，利用固/气界面聚合制备了均相薄膜。实验结果表明，利用该方法制备出的P(BT-4EDOT)薄膜具有良好的电化学活性及电致变色性能。关键词：导电聚合物；PEDOT；固/气界面聚合；电致变色中图分类号：O631文献标志码：A文章编号：2096-854X（2022）06－0024-04PreparationofPEDOTDerivativesbySolid/GasInterfacialPolymerizationandItsElectrochromicPropertiesStudyLiYu1，+，XuWenyuan1，+，LiHui2，XiongZhenhua1，*，ZhangGe1，*(1.SchoolofChemistryandChemicalEngineering,JiangxiScienceandTechnologyNormalUniversity,Nanchang330013,Jiangxi,P.R.China;2.SchoolofPharmacy,JiangxiScienceandTechnologyNormalUniversity,Nanchang330013,Jiangxi,P.R.China)Abstract:Poly（3-ethylenedioxythiophene）（PEDOT）,asoneofclassicalconductivepolymers（CPs）,hasabroadapplicationmarketinthefieldofelectrochromism.AlthoughthepreparationofPEDOTanditsderivatives（PEDOTs）bytheconventionalchemicaloxidationmethodislow-costandfast,theobtainedpolymersarepowdered.Thesepowdershavepoorsolubilityincommonsolvents,sohigh-qualityfilmscannotbeobtainedbyfurtherprocessing.Somehigh-qualityPEDOTsfilmscanbepreparedbyvapor-phasepolymerization（VPP）technology,butthistechnologyislimitedtosmallorganicmoleculesthatcanbevaporized.Soaderivativeof3,4-ethylenedioxythiophene（EDOT）,BT-4EDOT,wasdesignedinthiswork.ReferringtoVPPtechnology,thispaperpreparedhomogeneousfilmsthroughgas-interfacepolymerization,whichreplacestheprocessofmolecularvaporizationwithspraying.TheexperimentalresultsshowthattheP（BT-4EDOT）thinfilmspreparedbythismethodhavegoodelectrochemicalactivityandelectrochromicproperties.Key...
