在乙腈/三氟化硼/乙醚(CH3CN/BF3/EE)体系中，以四丁基四氟硼酸铵为催化剂，在1.4V恒压电解条件下，实现了呋喃的电化学聚合。采用循环伏安法研究了呋喃在不同比例混合溶剂中的电化学行为。在CH3CN/BF3/EE混合气(2/4/4；v/v/v)中制备了自支撑聚呋喃(PFU)薄膜，并用FTIR光谱技术对其进行了表征。通过原位记录电子吸收光谱，研究了PFU膜在无单体溶液中的光谱电化学行为。结果表明，与银丝(灰色)相比，PFU薄膜可以在-0.1V(灰色)和+0.6V(灰色)之间进行可逆循环；但是，在水存在的情况下，这种行为会减弱。研究了聚乙二氧基噻吩基PFU薄膜电致变色器件的应用。#2006威利期刊，Inc.应用理科杂志103：871-876,2007
Electrochemical polymerization of furan was achieved in acetonitrile/boron trifluoride/ethyl ether (CH3CN/BF3/EE) mixture in the presence of tetrabutylammonium tetrafluoroborate via constant potential electrolysis at 1.4 V versus Ag/AgCl. Electrochemical behavior of furan was investigated in the same solvent mixture of varying ratios, utilizing cyclic voltammetry. Free-standing polyfuran (PFu) films were obtained in CH3CN/BF3/EE mixture (2/4/4; v/v/v) and characterized using FTIR spectroscopic technique. Spectroelectrochemical behavior of the PFu film was investigated by recording the electronic absorption spectra, in situ, in monomer-free solution. It is observed that PFu film can be reversibly cycled between –0.1 V (gray) and + 0.6 V versus Ag-wire (gray color); however, this behavior diminishes in the presence of water. Electrochromic device application of PFu film with poly(ethylene dioxythiophene) was also studied. © 2006 Wiley Periodicals, Inc. J Appl Polym Sci 103: 871–876, 2007
