| Abstract: Fe3O4 nanoparticles were prepared by chemical co-precipitation using palmitic acid as surfactant， then a uniformly dispersed system of Fe3O4@Polymethylmethacrylates(PMMA) core-shell structure was obtained. Furtherm-ore， polymethylmethacrylates(PNIPAM) was encapsulated on the surface of the Fe3O4@PMMA core-shell nano-structure to get Fe3O4@PMMA@PNIPAM double shell-core composite structure. After that， the Ag nano-particles were assembled on the surface of Fe3O4@PMMA@PNIPAM taking advantage of coordination reaction between Ag+ and nitrogen atom on the amide group of PNIPAM. The magnetism of composites is convenient for the catalyst separation from the solution. |
