Abstract
A gecko-inspired silicone rubber array was successfully fabricated by ICP etching strategy. Adhesion properties of this gecko-inspired structure were studied through two parallel and independent approaches: experiments and model simulations. In our former work, based on the JKR (Johnson-Kendall-Roberts) contact theory, we proposed a nonlinear mechanical model to formulate the adhesion between a fiber and substrate. Now SPM experimental results verify the maximum adhesion force; show that fiber structure has being relatively better adhesion than unstructured. Moreover, some experimental phenomena explained by our present model.
