Abstract

original image

Nanoscale interfaces that form between two immiscible liquids can be harnessed to create patterned nanoarray structures. Pattern formation is achieved with nanodrop effusion of an uncured prepolymer of polydimethylsiloxane by mechanically compressing the wrinkle-patterned mold, followed by UV-assisted molding of the nanodrops with a different prepolymer of poly(urethane acrylate), resulting in the formation of ordered nanohole arrays over a large area.
