摘要:
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.

Methods for fabricating a nanopillared substrate surface include applying a polymer solution containing an amphiphilic block copolymer and a hydrophilic homopolymer to a substrate surface. The amphiphilic block copolymer and the hydrophilic homopolymer in the polymer solution self-assemble on the substrate surface to form a self-assembled polymer layer having hydrophobic domains adjacent to the substrate surface and hydrophilic domains extending into the self-assembled polymer layer. At least a portion of the hydrophilic domains may be removed to form a plurality of pores in the exposed surface of the self-assembled polymer layer. A protective layer may be deposited on the exposed surface as a mask for etching through the plurality of pores to form through-holes. A nanopillar-forming material may be deposited onto the substrate surface via the through-holes. Then, the remaining portion of the self-assembled polymer layer may be removed to expose a nanopillared substrate surface.
