在0.5mol/LH2SO4水溶液中,以氧化铟锡(ITO)导电玻璃为工作电极,用恒电位电解的方法,在0.9V电位下电化学共聚邻甲基苯胺(OT)和邻氨基苯甲酸(AA).涉及的电化学聚合均用在线紫外-可见光谱进行跟踪,结果表明电化学共聚随着反应体系中邻氨基苯甲酸的浓度的增加而变慢;所得的均聚物和共聚物均用FTIR和扫描电镜表征.FTIR表明邻甲基苯胺和邻氨基苯甲酸之间发生了共聚;扫描电镜图表明,与聚邻甲基苯胺相比,从200mmol/LOT/50mmol/LAA和150mmol/LOT/50mmol/LAA反应体系得到的共聚物具有小颗粒和较为致密的表面形貌;这个现象也帮助证明了邻氨基苯甲酸应该与邻甲基苯胺发生了共聚,并使表面形貌发生了改变.
In 0.5 mol / LH 2 SO 4 aqueous solution, indium tin oxide (ITO) conductive glass was used as the working electrode. Electrochemical copolymerization of o-methylaniline (OT) and anthranilic acid (AA ). The electrochemical polymerization involved was followed by in-line UV-Vis spectroscopy. The results showed that the electrochemical copolymerization slowed down with the increase of anthranilic acid concentration in the reaction system. The homopolymers and copolymers obtained were characterized by FTIR And scanning electron microscopy (SEM) .FTIR showed that o-methylaniline and anthranilic acid copolymerized. Scanning electron micrographs showed that from 200mmol / LOT / 50mmol / LAA and 150mmol / L OT / / LAA reaction system obtained copolymer with a small particle and a more dense surface morphology; this phenomenon also helps prove that anthranilic acid should be o-methylaniline copolymerization, and the surface morphology has changed.
