Patent number: 9566609Abstract: Methods for replicating a nanopillared surface include applying a nanopillar-forming material to a surface of a replica substrate to form a precursor layer on the replica-substrate surface. A template surface of a nanomask may be contacted to the precursor layer. The nanomask may include a self-assembled polymer layer on a nanomask-substrate surface, the template surface being defined in the self-assembled polymer layer. The self-assembled polymer layer may have nano-sized pores with openings at the template surface. The precursor layer may be cured while the template surface remains in contact with the precursor layer. The nanomask is removed to expose a nanopillared surface having a plurality of nanopillars on the replica-substrate surface. The nanopillars on the replica-substrate surface may correspond to the pores in the template surface. Nanopillared surfaces may be replicated on one side of the replica substrate or on two opposing sides of the replica substrate.Type: GrantFiled: January 24, 2013Date of Patent: February 14, 2017Assignee: Corning IncorporatedInventors: Jennifer Lynn Lyon, Jianguo Wang, Ruchirej Yongsunthon, Ying Zhang
