Abstract

Using electrochemical deposition of tungsten oxide from a metastable acidic solution of isopolytungstates into a poly(3,4-ethylenedioxithiophene) film, composite films were obtained on optically transparent electrodes made of fluorine-doped tin oxide on glass. In situ electronic spectra of poly(3,4-ethylenedioxithiophene)–tungsten oxide composite films and their components, poly(3,4-ethylenedioxithiophene) and tungsten oxide films, were studied using the spectroelectrochemistry method at various electrode potentials. The good additivity of the spectra of the composite and its constituent components suggests that there is no pronounced specific chemical interaction between the components, except for the electrostatic interaction between positively charged polymer fragments and negatively charged polymer oxo anions of tungsten oxide.

稀硫酸溶液中聚（3,4-乙撑二氧噻吩）-氧化钨复合薄膜的光谱电化学

摘要

通过将氧化钨从异多钨酸的亚稳态酸性溶液中电化学沉积到聚（3,4-亚乙基二氧噻吩）薄膜中，在玻璃上由掺氟氧化锡制成的光学透明电极上获得了复合膜。原位使用分光电化学方法在各种电极电势下研究了聚（3,4-亚乙基二氧噻吩）-氧化钨复合膜及其组分聚（3,4-亚乙基二氧噻吩）和氧化钨的电子光谱。复合材料及其组成成分的光谱具有良好的可加性，表明成分之间没有明显的特定化学相互作用，除了带正电的聚合物碎片和带负电的氧化钨聚合物氧代阴离子之间的静电相互作用。
