摘要：

Phase behavior of semiflexible-flexible diblock copolymer melt with conformational asymmetry epsilon >= 1 is studied by means of mesoscale modeling. It is shown that phase behavior of melt with epsilon = 1 follows predictions from self-consistent field theory while symmetry of phase diagram is broken for melts with epsilon > 1. Moreover, increasing of epsilon leads to replacement of gyroid nanostructure by more stable cylindrical and lamellar nanostructures. Our results are in agreement with experimental observations.
