  • FABRICATION OF NANO-PATTERNED SURFACES FOR APPLICATION IN OPTICAL AND RELATED DEVICES
    Publication number: 20220365248
    Abstract: The invention provides a solution based process based on high molecular weight block copolymer (BCP) nanolithography for fabrication of periodic structures on large areas of optical surfaces. In one embodiment there is provided method of fabricating a nano-patterned surface for application in a photonic, optical or other related device, said method comprising the steps of: providing a substrate material; depositing a block copolymer (BCP) material on the substrate material; and phase separating the BCPs using at least one solvent selected to facilitate polymer chain mobilisation and lead to phase separation to fabricate said nano-patterned surface; wherein the nano-patterned surface comprises an ordered array of structures and having a domain or diameter of 100 nm or greater. A new photonic device and optical device is also described.
    Type: Application
