Facile Fabrication of Ordered Nanostructures from Protruding Nanoballs to Recessional Nanosuckers via Solvent Treatment on Covered Nanosphere Assembled Monolayers

We present a facile lithographic
nanosphere production process
by laminating a nanosphere monolayer with a UV resin and applying
various gentle solvent treatments to produce “bottom-up”
and “bottom-down” nonclose-packed patterns and investigate
their practical applications in nanolenses for optical display and
nanosuckers for adhesion. The solvents effect depending on its solubility
parameter and solubility tendency toward the interior polystyrene
nanospheres was discussed. The polymer-based nanosucker pattern displays
shear adhesion force as high as 75.2 N/cm2.
