Vertically Aligned Multiwalled Carbon Nanotube Arrays

Inspired by the geckos’ ability of climbing on all kinds of natural surfaces, a novel dry adhesive is being developed that can mimic the hairs on a gecko’s foot using vertically aligned multiwalled carbon nanotube (CNT) array. The use of CNT array as dry adhesive material allows reproducing biological adhesion structures and generates fairly strong adhesion strength (over 100 N/cm2). This is because vertically aligned multiwalled carbon nanotube arrays have a structure similar to biological adhesive surfaces with even smaller feature sizes.
