银配位聚醋酸乙烯酯的制备与表征

Preparation and characterization of silver coordination polymer Ag/PVAc

以聚醋酸乙烯酯(PVAc)为基体,与Ag(Ⅰ)反应形成配合物后,选择适宜的还原剂、反应条件,制备出新的金属配合物Ag/PVAc复合材料。通过控制反应基体和金属离子的反应温度、反应时间等工艺条件,得到纳米级金属Ag/PVAc颗粒。采用XRD、SEM、IR、UV等对复合材料的粒径分布、晶相结构以及键合方式等进行研究。

Ag/PVAc was synthesized by using Poly(vinyl acetate)(PVAc) and Ag(Ⅰ) to form complexes, and by selecting appropriate reducing agent, reaction conditions. By controlling the process conditions, such as the reaction time of PVAc and metal ions, the reaction temperature etc, the nano-metals Ag/PVAc particles was prepared. By using characterization means of XRD, SEM, IR, UV, the particle size distribution, crystalline morphology and structure, bonding method of composite material were researched.
