Phase transition and self‐assembly in block copolymers

We focussed on the following two topics on block copolymers; (i) the Brazovskii effects, effects of thermal fluctuations on phase transition of systems having a short characteristic length L, and (ii) nanofabrication and nanohybrids based on block copolymer nanostructures. We highlight the following two aspects: Block copolymers provide good model systems for studies of basic physical science and are useful for advanced functional materials and devices.
