Abstract
The microphase transitions of a nanorod/diblock copolymer composite under steady shear flow are investigated via dissipative particle dynamics. The aim of our study is to understand how the anisotropic nanorods affect the structure of diblock copolymer melts and how the shear flow induces the dynamic behaviors of the composites. We investigate two effects: one is nanorods concentration, and the other is nanorods length. Finally, we compare the rheological properties of different conditions and observe the oriention of nanorods. Our results show that Janus nanorods can not only reinforce the material, but also reduce fluctuation of the structure. Therefore, we can’t observe perpendicular lamellae at high nanorods concentrations. Additionally, we also observe that nanorods with longer length will be more disorder owing to the repellence between the nanorods and thus decrease the viscosity of the composites. In this research, we provide a viable approach to create functional materials with enhance processing properties.
