Meso-scale modeling of block copolymer/colloid nano-composites

We develop a coarse grained simulation technique to study dynamics in soft nano-composites. The system consists of block copolymer melt or solution with nano-size colloidal particles. The time evolution of the system is described by a multiscale approach: a field based simulation for block copolymer component and a particle based method for nano-colloids. The block copolymer is modelled by cell dynamics simulation technique, and colloids are modelled in a spirit of dissipative particles dynamics. A cross interaction term is controlling the interplay of dynamics of both components. The influence of colloids on block copolymer morphology is investigated.
