Fund Project: Thanks are due to Dr Chun Xiang XU for helpful discussions (Department of Electronic Engineering, Southeast University). This work has been supported by the Talent Foundation of Southeast University.

The phase behavior of a well-defined poly (methyl methacrylate)-b-polystyrene block copolymer was studied by transmission electron microscope.The results show that a microphase transition may have occurred in the copolymer film.A kind of lamellae and an ordered bicontinuous double-diamond morphology are observed clearly.The lamellar morphology reveals a larger period of about 400 nm.
