Gecko has ability to climb up easily on smooth vertical surface such as window glass. There are thousands of nano size hairs on the Gecko's feet. They cause strong attractive van der Waal’s force. Aihara and Chibana suggested the Super Gecko structure in which the normal polyethylene (PE) molecules are vertically transplanted on a plate. Two of this structure are interlocked like as zip fastener. In present study, self-formation process of the Super Gecko structure is simulated by molecular dynamics (MD) method. The separated Super Gecko structures with distributed electric charge on the PE molecules form the zipped Super Gecko structure on oneself. The opposite electric charges cause attractive force between two separated structures. The size dependency of self-formation of Super Gecko structure is simulated.
