제목 Liquid Crystalline Phase Behavior of Hydrophilic Gold Nanoparticles induced By Pluronic Triblock Copolymer 
초록 The gold nanoparticles (AuNPs) having unique optical and electrical properties, are being explored widely for use in a nanotechnology application such as bio-imaging, electronic conductor, and radiotherapy. Herein, the influence of adding CTVB (cetyl trimethylammonium bromide) tethered AuNPs on the phase behavior of highly concentrated amphiphilic triblock copolymer pluronic P85, P104, F127, PE6200 and PE6400 in H2O was investigated. For the size monodispersity and aqueous stability of the particles, we further functionalized the AuNPs (p-AuNP), and as using these hydrophilic fabricated spherical particles, highly ordered self-assembled complexes were successfully made. The liquid crystalline phase transition as increasing temperature below 85 °C, with various p-AuNP weight fraction, have been studied by using in-situ small-angle X-ray scattering(SAXS) experiments.
