Abstract
In this study, we demonstrate a novel gold/PMMA hybridizing spherical nano ball and nano network structures. The linear polymer, poly (methyl methacrylate)(PMMA, MW = 15,000 g/mol) not only represents the stabilizer of gold nanoparticles, but also represents the bridge of neighbors gold nanoparticles during the synthesis procedures. The Fourier Transfer Infrared (FTIR) analysis data and Transition Electron Microscopy (TEM) image reveal that the core shell structure of gold/PMMA nanocomposite has been synthesized. With increasing the salt concentration via the increasing of ion-strength in the synthetic media, the core-shell structures would be fluctuation in the form of “dung worm”. After drying treatment, the TEM image reveals that the network structures of PMMA capped gold nanoparticles have been formed. With specific amount of PMMA presence in synthesis media, a single population of gold/PMMA hybridizing spherical nanoball was synthesized.We synthesize gold nanoparticle, which was gold/PMMA hybridizing spherical nanoparticle. The linear polymer, poly (methyl methacrylate)(PMMA, MW = 15,000 g/mol) not only represents the stabilizer of gold nanoparticle, but also represents the bridge of neighbors gold nanoparticles during the synthesis procedures. It can also control gold nanoparticle size by different amount of PMMA. We put different size gold nanoparticle into electron beam resist. It can reduce charging effect by adding gold nanoparticle into electron beam resist.
