Abstract Conducting polymer composite films containing poly(3,4-ethylenedioxythiophene) (PEDOT) was prepared by solid state polymerization (SSP) of 2,5-dibromo-3,4-ethylenedioxythiophene (DBEDOT) in the matrices of polystyrene (PS), sulfonated polystyrene (SPS), or poly(methyl methacrylate) (PMMA). A thin fiber mat was first fabricated by electrospinning a mixed solution of the polymer matrix and DBEDOT on glass slides. The SSP of the DBEDOT embedded in the polymer matrix was then induced by heating at 60–80 °C, which resulted in a dark blue PEDOT composite film, structurally confirmed by Raman spectroscopy and X-ray diffraction spectroscopy. It was found that compression during heating produced better dispersed PEDOT particles in the polymer matrix. The conductivity of the composite fiber was found to reach as high as approximately 13, 14 and 32 S/cm for the PEDOT/PS, PEDOT/SPS and PEDOT/PMMA composite films, respectively. These conductivity values are comparable to that of the pure PEDOT generated directly by SSP in the absence of a polymer matrix.

静电纺丝和固态聚合：一种简单而通用的 PEDOT 复合薄膜导电途径

摘要 采用 2,5-二溴-3,4-乙撑二氧噻吩 (DBEDOT) 在聚苯乙烯 (PS) 基质中进行固态聚合 (SSP) 制备含有聚 (3,4-乙撑二氧噻吩) (PEDOT) 的导电聚合物复合薄膜，磺化聚苯乙烯 (SPS) 或聚（甲基丙烯酸甲酯）（PMMA）。首先通过在载玻片上静电纺丝聚合物基质和 DBEDOT 的混合溶液来制造薄纤维垫。然后通过在 60-80°C 下加热来诱导嵌入聚合物基质中的 DBEDOT 的 SSP，从而产生深蓝色 PEDOT 复合膜，结构由拉曼光谱和 X 射线衍射光谱证实。发现加热期间的压缩在聚合物基体中产生更好分散的PEDOT颗粒。发现复合纤维的电导率高达约 13，对于 PEDOT/PS、PEDOT/SPS 和 PEDOT/PMMA 复合薄膜，分别为 14 和 32 S/cm。这些电导率值与在没有聚合物基质的情况下由 SSP 直接产生的纯 PEDOT 的电导率值相当。
