直鎖ポリエチレン同士の接合における接合強度の分子動力学的解析

抄録

Geckos have ability to climb easily and speedy up smooth vertical surface such as window glass. Gecko's foot has thousands of nanometer size hairs. They cause strong attractive van der Waals force. In present study, adhesion between surface structures similar to Gecko's foot is simulated by molecular dynamics (MD) method. Normal polyethylene (PE) molecules are vertically transplanted on a carbon plate. Two of this structure are interlocked like as zip fastener. The authors name this connected structure “Super Gecko model”. Simulated strength of Super Gecko model is a function of surface density of PE and temperature.
