Abstract
In the microphase separation of block copolymers, it is known to form polygrain structures. In a single grain, the microphase-separated domains order in the same periodicity and orientation, while the orientation of each grain is different from each other. At the boundary of grains, the microphase-separated domains are supposed to form "grain boundary strcture" which is different from the equilibrium structure in order to minimize the interfacial free energy between the grains with different orientations. In this study, the structures at lamellar grain boundary were studied by transmission electron microtomography (TEMT). A structure similar to the Scherk's surface which is considered to be a typical model structure for lamellar grain boundary, was found.
