Abstract Optically transparent and highly conductive poly(3,4-ethylenedioxythiophene) (PEDOT) thin films were grown through vapor phase polymerization on (3-Mercaptopropyl)trimethoxysilane functionalized 3,4-Ethylenedioxythiophene (MPTMS functionalized EDOT) grafted glass substrates. Compared to bare glass, the EDOT grafted surface led to enhancements in both electrical conductivity and adhesion of PEDOT thin films. A quinoid-rich structure with increased crystallinity and a further enhanced conductivity was induced by post-deposition sulfuric acid doping. X-ray diffraction showed different orientations of the PEDOT crystals grown on substrates with and without EDOT grafting. The highest conductivity of 2690 S/cm, with an average optical transmittance of 95.4 % in the visible range, was achieved when PEDOT was vapor phase polymerized on EDOT grafted substrates and doped with 98 % sulfuric acid. Photostability was tested using a xenon arc light source and characterized by attenuated total reflection Fourier-transform infrared spectroscopy, showing that photo-induced degradation is associated with a decrease in C C double bond content.

气相聚合PEDOT界面改性对玻璃基板的影响

摘要 通过气相聚合在（3-巯基丙基）三甲氧基硅烷功能化的 3,4-乙烯二氧噻吩（MPTMS 功能化 EDOT）接枝玻璃基板上生长了光学透明且高导电性的聚（3,4-亚乙基二氧噻吩）（PEDOT）薄膜。与裸玻璃相比，EDOT 接枝表面提高了 PEDOT 薄膜的导电性和附着力。沉积后硫酸掺杂诱导了富含醌类结构，结晶度增加，导电性进一步增强。X 射线衍射显示在有和没有 EDOT 接枝的基板上生长的 PEDOT 晶体的不同取向。最高电导率 2690 S/cm，可见光范围内平均透光率为 95.4%，当 PEDOT 在 EDOT 接枝基材上进行气相聚合并掺杂 98% 的硫酸时，就实现了。使用氙弧光源测试光稳定性，并通过衰减全反射傅立叶变换红外光谱进行表征，表明光致降解与 CC 双键含量的减少有关。
