Patterned Polymeric Domes with 3D and 2D Embedded Colloidal Crystals using Photocurable Emulsion Droplets

Hierarchical dome patterns are prepared via a novel single-step patterning process. Photonic domes with isotropic reflection colors are patterned on a prepatterned glass substrate with a hydrophobic moiety using photocurable emulsion droplets of all-equal size, which contain concentrated silica particles. Furthermore, embossed domes are patterned with PS particle-stabilized photocurable emulsion droplets, which can act as a near-field microlens array.
