Abstract Nano Ga–Pd/poly methyl methacrylate (PMMA) composite materials were prepared with the palladium chloride solution containing metal galliumMMA 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.
