Preparation of biomimetic high adhesive superhydrophobic polymer pillar surfaces with crown-like metal microstructures

High adhesive superhydrophobic polymer pillar surfaces with dispersed metallic crown-like micro structures were prepared by electroless plating on self-organized honeycomb patterned polymer films and peeling off the top layer of the metal covered honeycomb films. Thus obtained polymer pillar surfaces with metallic crown-like microstructures possessed conflicting properties of water repellency and adhesion. The adhesion property was tuned by number density of metallic crown-like microstructures which were adjusted by polymer concentration in a catalytic solution for electroless plating.
