摘    要:在不使用引发剂和还原剂条件下,用超声辐射工艺双原位合成了纳米钯镓/聚甲基丙烯酸甲酯(PMMA)复合物.XRD和UV-Vis显示,超声还原生成的单质钯和超声粉碎的单质镓在PMMA基体中不是简单的物理分散,而是在生成钯镓合金Ga5Pd/PMMA复合物的同时既有纳米钯又有纳米镓与PMMA形成复合物;XPS表明,镓失去了部分外...

Abstract:Nano Ga-Pd/poly methyl methacrylate(PMMA) composite materials were prepared with the palladium chloride solution containing metal gallium、MMA as monomer without initiator or reducer. Results show that there are Pd,Ga,and Ga5Pd phase in PMMA matrix.There was a characteristic absorption peak at 200 nm for nano-Ga/PMMA polymer solution,at 209 nm for nano-Pd/PMMA polymer solution,and the absorption peak of nano Pd-Ga/PMMA shiftted to long wavelength at 218 nm;Nano Ga5Pd formed based on segment electronics shifting from gallium to palladium,and coordination formed found on part electronics diverted from gallium to oxygen of PMMA ester group.PMMA possess anisotropic ordered microstructure around nano Ga-Pd particles,illustrating that there are interaction between nano Ga-Pd particles as dispersive and PMMA as continuous phase.
Keywords:composites  nano Pd-Ga  PMMA  ultrasonic  interface structure  nanocomposite
