Abstract
Surface characteristics of the tricontinuous structure of a triblock c opolymer of the ABC type in bulk has been studied. An isoprene-b-styre ne-b-2-vinylpyridine (ISP) triblock copolymer, whose total molecular w eight is 100 K and the volume fractions of the three components are 0. 26, 0.48 and 0.26, respectively, was used as a sample in this study. I t turned out clear by comparison of transmission electron microscopy ( TEM) and computer simulation (CS) studies and also by small angle X-ra y scattering (SAXS) that the A/B and B/C interfaces of ABC copolymers have the characteristics of the parallel surfaces with constant-mean-c urvatures, which are derived from the Schoen's G-surface, which is one of the minimal surfaces.
