dc.description.abstractWe have systematically studied the macroscopic adhesive properties of vertically-aligned nanotube arrays with various packing density and roughness. Using a tensile set-up in shear and normal adhesion, we find that there exists a maximum packing density for nanotube arrays to have adhesive properties. Too highly-packed tubes do not offer inter-tube space for tube bending and side-wall contact to surfaces, thus exhibiting no adhesive properties. Likewise, we also show that the surface roughness of the arrays strongly influences the adhesion properties and the reusability of the tubes. Increasing the surface roughness of the array strengthens the adhesion in the normal direction, but weakens it in the shear direction. Altogether, these results allow progress towards mimicking the gecko’s vertical mobility. carbon nanotube forests
