摘要
Abstract
The self-assembled phase behaviors of lamellar block copolymers and nanorods mixtures were investigated by dissipative particle dynamics(DPD) simulations. A series of parameters, such as nanorod concentration, length, and the polymer-nanorod interaction, are introduced to analyze the cooperative phase behavior and novel morphologies of hybrids. The final phase structures of the mixtures result from the mutual inducement between mesophase-forming copolymers and nanorods aggregates. When nanorods are mixed into the polymer fluids, it is used for understanding the intrinsic characteristics of the composite self-assembly by considering the enthalpic and entropic interactions, especially for the rods' phase behaviors. The nanorods distributions reveal a degree of enthalpically driven self-assembly, due to the interactions among species. The nanorods' orientation show a degree of entropically generated self-assembly, based on the competition among the inherent shape anisotropy of nanorods, confinement of Host phase separated domains, and the conformational entropy of chains.关键词
