21_22b/2009Polymeric Nanohairs: Stooped Nanohairs: Geometry-Controllable, Unidirectional, Reversible, and Robust Gecko-like Dry Adhesive (Adv. Mater. 22/2009)

Kahp Suh, Hong Lee, and co-workers present on p. 2276 a simple, yet robust method for fabricating an array of stooped “nanohairs” by applying a proper choice of materials and post e-beam exposure, even for an aspect ratio of 10. The stooped nanohairs possess the unidirectional feature of frictional adhesion with a remarkably high adhesion force (∼11 N cm−2).
