Abstract
A high-density array of barnacle-like porous structures was fabricated using monolayers of polystyrene spheres and various types of poly(vinyl alcohol). We first prepared the polystyrene sphere monolayer as a close-packed hexagonal array on a glass substrate. The monolayer was then etched using a plasma treatment to isolate each sphere. Next, we spin-coated the isolated spheres with a water solution of poly(vinyl alcohol). After drying, we applied a second short plasma treatment to the substrate before immersing it in a toluene bath, which promoted opening formation due to polystyrene swelling. As a result, a high-density array of barnacle-like porous structures was homogenously formed on the substrate. These porous structures are expected to be used for various applications including functional coatings, protective cell cultures, and sensor chips.
