摘要
Self-assembly behaviors of rod-coil-rod triblock copolymers in the selective solvent are systematically investigated by dissipative particle dynamic simulations. Three selective solvents are considered: the pure coil-selective solvent, the pure rod-selective solvent, and the mixed solvent. The concentration-induced morphologies and morphological transition affected by the rod and coil length are examined. The micelle adopts the overall shape of sphere, nematic bundle, worm, cylinder, lamella, coil-, and rod-aggregated hollow cylinders, and network. In the coil-selective solvent, increasing coil length can defer the phase transition from sphere to other morphologies while increasing rod length can advance the transition. In the rod-selective solvent, an opposite influence rule is found.
