Fabrication of nano hair having hierarchy structure imitating gecko and evaluation of adhesion force

Abstract

In this report, in order to prepare adhesion mechanism that imitated gecko, we worked on the fabrication of fine hair using 3D stereolithography equipment and AAO . We succeeded in actually fabricating nano-sized fine hair and two layer structure. We measured adhesion fine hair produced. In the measurement method, fine hair was attracted to the film of Parylene and it was pulled to bend the film, and the adhesion force was evaluated from the amount of deflection. Fine hair having a two-layer structure showed adhesion power, and it was confirmed that the mechanism of gecko was effective in adhesion of Van der Waals force.
