摘要
利用原位LPSIRS技术获得氢氧化钠甲醇溶液中2,6-二甲基苯酚在金电极上电聚合的红外光谱信息,从而推测2,6-二甲基苯酚在金电极上电聚合机理是一系列交替着的离子、游离基步骤。
This paper reported application of In Situ LPSIRS (linear potential sweep infraredreflectance spectroscopy) technique to get precise spectroscopy information aboutelectropolymerization of 2,6-dimethylphenol on gold electrode in base methanolsolution and propose the electropolymerization mechanism under the conditions. Fromthe spectra it has been found that the DMP^- ion was cosumed and PPO polymer wasproduced during cyclic voltammetry. At the same time, it has been deduced that themethanol in the case probably takes part in the electropolymerization partly. Theelectropolymerization mechanism of 2, 6-dimethylphenol in base methanol is a sequenceof alternating ionic and radical steps; the propagation occurs by coupling of twophenate radicals.
