| 摘 要： | 利用反射吸收红外光谱法(RAIR)研究了两种乙烯基共聚物与金属(铜,铁)复合体系界面的化学结构特征.研究表明,乙烯-醋酸乙烯共聚物(EVA)中羰基峰在EVA与金属作用时分裂产生双峰,自由羰基峰与金属发生络合反应而向低波数方向移动;同时证明EVA中羰基垂直作用于金属表面.对乙烯-甲基丙烯酸共聚物(EMAA)与金属复合界面的研究表明,在EMAA与铁复合体系的界面层中有络合物生成,而EMAA与铜的体系有羧酸盐离子产生.

| Abstract: | Interfacial interactions of vinyl copolymer (ethylene vinyl acetate copolymer and ethylene methyacrylic acid copolymer) coated on metal (Cu and Fe) were investigated with the Reflection Absorption Infrared Spectroscopy (RAIR). Results show that the carbonyl group absorbed onto the metal surface in EVA is prefer to perpendicular to the surface and the peak of carbonyl group in pure EVA is split when it interacts with the metal forming complex structure. It also certificates that complex structure is formed in the interface of ethylene macrylate acid/Fe composite and carboxylate anions is formed by charge transfer in the interface of the copper and the ethylene methylacrylic acid copolymer. |
