Metal nanocomposites have different optical/electrical properties depending on their size, shape, and morphology because of effect of surface plasmon resonance (SPR). Gold-nanoparticles (AuNPs) as one of them with unique optical/electrical properties have being widely applied to photodevice, optical sensor, and drug delivery. We have tried to form the stable AuNPs in aqueous solution, which has hydrophobic surface. These AuNPs entrapped by other molecule as a surfactant, they be stably dispersed in aqueous solution by the surfactant molecule. In this study, we investigated the nanostructure of entrapped AuNPs using by the surfactant of cetyltrimethylammonium 4-vinyl benzoate (CTVB). We made several mixtures of entrapped AuNPs and amphiphilic molecule, which mixtures are controlled by AuNP concentration. The small-angle X-ray scattering (SAXS) measurements results showed that these AuNPs mixtures have highly ordered structures. |
