Bioinspired Surfaces I: Gecko‐Foot Mimetic Adhesion

Controlled droplet transport on a gradient adhesion surface

“…[10][11][12][13][14][15][16] Moon Kyu Kwak et al 1 developed a technique to fabricate nano-hairs by using a rigiflex poly(urethane acrylate) mold material to generate different kinds of slanted nanohairs, which can tune the directional adhesion properties. Dai et al 17 prepared aligned multi-walled carbon nanotubes combined with a shape-memory polymer to tune the adhesion. Herna ´ndez et al 18 fabricated a well-controlled, chemical gradient surface of a graphene substrate to push the directional motion of a droplet.…”
