A well-defined 3D bicontinuous network structure in nanoscopic regular array has attracted considerable attention because of its potential applications such as photonic crystals, meta-materials, energy devices and superconductor. In this study, the asymmetric polystyrene-block-poly (methyl methacrylate) (PS-b-PMMA) thin films on the two different substrate with highmolecular-weight were prepared to be exposed a neutral solvent vapor to generate a hexagonal (HEX) cylindrical morphology to long-range ordered Gyroid (GYR). The interfacial interaction by different substrate interaction induced the two distinct GYR, [211] and [111] planes, which were directed from cylinders, like the parallel and perpendicular orientation on the selective and neutral substrate, respectively. Moreover, we further performed coarse-grained simulations of a block copolymer model to provide the molecular mechanisms. Our results based on experiments and simulations suggest a simple route for the controlled and well-defined GYR structures.
