Title: Effect of Addtion of Nano-ZnO after Surface Modification to PEG Crystallization
Abstract: The nano-ZnO and ZnO after surface modification are added into PEG solution,the effect of nano-particles to PEG crystallization are observed.The result shows,the crystallization shape changes after adding nano-ZnO,with the increasing of carboxyl content on nano-particles surface,the crystallization shape changes on the low tree crystal,large spherulite and small spherulite.The FTIR measurements indicate that esterification reaction occurres between the hydroxyl-terminated of PEG and the carboxyl of nano-ZnO under thermal conditions,then,nano-ZnO can disperse in PEG solution stably,and provide nucleation point for the formation of spherulite.
