Abstract

An order-order transition (OOT) from the bicontinuous double-gyroid (G) structure to the hexagonally-packed cylindrical (C) structure in a poly(styrene-block-isoprene) (SI) block copolymer was investigated by transmission electron microtomography (TEMT). The coexistence of the G and C microdomains during the OOT was observed. The boundary structures between the G and C microdomains were directly three-dimensionally visualized. It was found that the {220} plane of the G structure changed to the {110} plane of the newlygenerated C structure, consistent with Matsen's prediction from his computer simulations based on self-consistent field (SCF) theory.
