聚合物基金属梯度复合材料的制备与结构研究

Study for the preparation and structure of metal-in-polymer gradient composite*

本文通过石墨阴极溶液涂膜法制得甲基丙烯酸-丙烯酸共聚物[P(MMA-co-MAA)]与环氧乙烷(PEO)的共混聚合物,并以其为基质制备了聚合物基铜金属复合膜(CPCFs)。在这一过程中,对所得溶胀阴极膜(SCF)进行半干燥处理后,用电化学方法使其还原以得最终产物。实验研究表明:(1)低P(MMA-co-MAA)含量会增强SCF的离子电导率;(2)还原反应中酸性环境会增强电导性;(3)水-乙醇共溶剂有助于增强电导率。偏光显微镜测试显示:poly(MMA-co-MAA)会影响PEO的结晶。X-射线衍射实验也证实了还原铜金属单质的存在。

In this paper, metal salt was dissolved in water - alcohol co - solvent with polymer blends. After drying, swelling composite film was obtained from the solution on top surface of a disk cathode and the films was electrochemically reduced. The investigation showed ： （ 1 ） lower content of hydrophobic polymer imparts higher ionic the conductivity ; （2） acidic condition in reduction improves the conductivity ; （ 3 ） water - alcohol co - solvent is more helpful to enhance the conductivity. Polarized optical microscopy observations indicated decrease of crystallization of PEO. X - ray diffraction confirmed the existence of reduced copper.
