Abstract

Nano-Ga-Pd/poly methyl methacrylate (PMMA) composite materials were prepared with the palladium chloride solution containing metal gallium, MMA as monomer, and sodium dodecyl sulfate (SDS) as emulsifier without initiatoror reducer. Pd, Ga, and phase in PMMA matrix were identified by XRD. The characteristic absorption peak at 200 nm for nano-Ga/PMMA polymer solution, at 209 nm for nano-Pd/PMMA polymer solution were proved by UV-Vis; the binding energy changes of O1s, Ga2p3, Ga2d, and Pd3d were characterized by means of X-ray photoelectron spectroscopy. It is concluded that nano- was produced based on segment electronics shifting from Gallium to Palladium, and coordination was formed on segment electronics from Gallium to oxygen of PMMA ester group. The anisotropism ordered assembly of PMMA around nano-Ga-Pd particles were illuminated by transmission electron microscopy; it is further interpreted that nano Ga-Pd particles had ordered-assembly induced effect.
