The ability to create any curved surface merely by imprinting its metric onto a flat sheet has great appeal for use in materials, manufacturing, and diagnostics applications. The effects of topological defects and anisotropic elasticity in a free standing monolayer of cylinder-forming diblock copolymers generate curved surfaces. Disclinations prove to be sources of Gaussian curvature, which when coupled with surface tension and elasticity, produce a long-ranged pattern of wrinkles perpendicular to the underlying smectic layers.
