3,4-乙撑二氧噻吩合成及其聚合物应用进展

Progress in the Synthesis of 3,4-ethyldioxythiophene and Its Polymer Application

3,4-乙撑二氧噻吩(EDOT)是导电聚合物——聚3,4-乙撑二氧噻吩(PEDOT)的单体。目前,国内EDOT的产量和品质等方面较国外有较大差距。因此,对EDOT的合成工艺进行深入研究有着重要的社会和经济效益。总结了EDOT的主要合成方法及其聚合物在防腐蚀涂层、超级电容器、钙钛矿太阳能电池、水凝胶等领域的应用与发展。

3,4-ethylenedioxythiophene(EDOT)is the monomer of conductive polymer—poly(3,4-ethylenedioxythiophene)(PEDOT).At present,there is a significant gap in the production and quality of domestic EDOT compared to foreign products.Therefore,conducting in-depth research on the synthesis process of EDOT has important social and economic significance.The main synthesis methods of EDOT and the application and development of its polymers in anti-corrosion coatings,supercapacitors,perovskite solar cells,hydrogels and other fields are summarized.
