| Research Abstract |
For smooth movement from static state, it prefers that kinetic friction coefficient is higher than static one. But the usual material shows opposite frictional property. The objective of this project is to develop a surface which performs smooth transient from static state to kinetic sliding state. We developed a nano-structured surface with densely-packed and vertically-aligned carbon nanotubes. The "brush" structure shows smooth transient from static to kinetic state. And this property is explained by concerning the bending of each carbon nanotubes from the results of observation of real contact area, surface morphology measurement, and nano indentation.
