Abstract Abstract A highly conformable long-range ordered double gyroid structure with the space group Ia3d is obtained by the self-assembly of a poly(2,2,2-trifluoroethyl methacrylate)-b-poly(2-vinyl pyridine) (PTFEMA-b-P2VP) diblock copolymer through solution casting. 9 different PTFEMA-b-P2VP samples are synthesized, each of which has a different mass fraction to others, with the product containing 47 wt% of PTFEMA exhibiting a double gyroid structure. Analysis of the transmission electron microscopy and scanning electron microscopy images of this product have revealed that the structural planes of the obtained 3D sample are in good agreement with the typical (211), (110), and (111) planes of the Ia3d space group, which is also supported by small angle X-ray scattering spectroscopy, therefore confirming that the samples formed a long-range double gyroid structure over a large area.
