Abstract
An ABC stacking type of the hexagonally perforated layered (HPL) structure of a diblock copolymer was reproduced using the self-consistent field (SCF) theory. Starting from this structure, the dynamics of the structural phase transition to a bicontinuous double-gyroid structure was studied using the time-dependent Ginzburg-Landau theory coupled with the Random Phase Approximation (GRPA). In the initial stage, the HPL structure starts to undulate and then one of the ABC layers strongly deforms to form three-fold junctions.
