Abstract :
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.
