Nanometer-size PMMA polymer network synthesis by gold nanoparticles template

In recent years, the interest in the synthesis and characterization of nanostructured materials has grown widely due to their distinctive physical and chemical properties. Recently, mono-dispersed nanoparticles protected by linear polymers were successfully synthesized of noble metal nanoparticles. Polymer protected, nano-size noble metals are receiving high attention, because they offer a high potential for many technological applications. In this study, the gold nanoparticles template was produced by chemical reduction of HAuCl/sub 4/ in the presence of NaBH/sub 4//PMMA (MW = 15,000 g/mol) reductant/stabilizer mixture media. Herein, the concentration of PMMA that affects the size and optical properties of gold particles is shown. The structure of PMMA/gold nanoparticles core shell was confirmed by TEM and FTIR.
