Abstract

Disclosed are methods of manufacturing a SH surface including: creating a master with SH features by: depositing a rigid material onto a first surface, wherein the first surface is a shrinkable platform; shrinking the first surface by heating to create a SH surface, wherein the SH surface has micro- and nano-scale structural features that trap air pockets and prevent water from wetting the surface; forming the master by molding an epoxy with the shrunken first surface having a SH surface, wherein the master acquires the SH features of the first surface; and imprinting the SH features of the master onto a second surface to impart the SH features of the master onto the second surface. Some embodiments relate to a superhydrophobic (SH) surface, an article including a SH surface as disclosed, such as a microfluidic device or a food container.
