Surface nanofabrication methods using self-assembled polymer nanomasks
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.
