摘要：

The grain boundary morphology of lamellar microdomains in block copolymers was investigated by means of transmission electron microscopy. A variety of patterns which can be successfully reproduced by the computer simulation using Scherk's first surface or deformed Scherk's first surfaces as a calculation model were observed. This implies that the microdomains with lamellar morphology which locally have only two-dimensional continuity are topologically continuous in three dimensional space as a whole through the grain boundaries, but the lamellae are essentially flat within the grains.
