| Abstract: | H 2PtCl 6 was coordinated with the carboxyl-terminated G4.5PAMAM dendrimer molecules (PAMAMC) in aqueous solution,followed by reduction using NaBH 4 as reducer,and formed Pt-PAMAMC hybrid nano-particles.The stable multilayer films were obtained by fabricating diazo resin(DR) with these hybrid nanoparticles (Pt-PAMAMC) and PAMAMC,respectively.The films were subsequently irradiated under UV-light.It was found that the films from Pt-PAMAMC as polyanions exhibit stable frictional responses under the applied load,and the lubricative property of the films from Pt-PAMAMC hybrid nanoparticles is obviously superior to that of the films from dendrimer without platinum inside. |
