Phase Transformation of Self-Assembled Nanostructure of PS-P2VP/HAuCl4 Hybrid System

POSTER

Abstract

In this study, we investigated the effect of the addition of chloroauric acid (HAuCl4) in polystyrene-b-poly (2-vinyl pyridine) (PS-P2VP) on the morphology and phase transformation of the mixture system. Nanosturcture of ordered array of spheres, cylinders, gyroids, lamellae as well as different shapes of micellar phases of the system can be obtained by choosing appropriate PS-P2VP diblock copolymer, by changing molar ration of the gold salt to the copolymer, and by choosing different solvents. The phase diagram of the hybrid system are determined and related to intermolecular interactions on nano- and mesoscopic scale. The self-assembled nanostructure is characterized by TEM, WAXS and SAXS.
