Primitive Chain Simulations of Block-copolymers under Flow

摘要

Block-ccpolymers are widely used and investigated to obtain materials with superior properties by combination of different polymers. It has been established that the properties are strongly dependent on the micro-phase structure of the materials. However, because the structure is affected by flow and deformation during processing, control of the properties is a challenging problem. In this study, micro-phase structure of block-copolymers was investigated under flow by a molecular based model called primitive chain network model. Distinctive advantage of the model is the explicit modeling of entangled systems which can not be taken account neither by the density functional methods nor by the dissipative particle dynamics method Promising results were obtained on the shear flow induced phase modification.
