A simple method for the preparation of nanomaterials with new functionality by physical displacement of a network phase is suggested, giving a change in space group symmetry and hence properties. A double gyroid structure made by the self‐assembly of block copolymers is used as a model system for the demonstration of shifting networks to achieve single gyroid‐like scattering properties. Free‐standing single gyroid‐like network materials can be fabricated to give nanophotonic properties, similar to the photonic properties of a butterfly wing structure.
