直鎖ポリエチレンからなるSuper Gecko構造のクーロン力による生成過程と接合強度の分子動力学的研究

抄録

Geckos have ability to climb up easily and speedy on smooth vertical surface such as window glass. Gecko's foot has thousands of nano size hairs. They cause strong attractive van der Waal’s force. Normal polyethylene (PE) molecules are vertically transplanted on a carbon plate. Two of this structure are interlocked like as zip fastener. Aihara and Chibana name this connected structure Super Gecko structure. In present study, formation process of the Super Gecko structure is simulated by molecular dynamics (MD) method. The Super Gecko structure has been formed from two separated structures consisting of the PE molecules with distributed electric charge which are vertically transplanted on a carbon plate. The electric charges cause attractive force between two separated structures.
