Abstract
<p>According to the law of friction, the maximum static frictional force is proportional to the normal force. A Carbon nanotube (CNT) is a nano-size, and flexible material. Vertically-aligned (VA)-CNTs, which are growing with a high density and vertically to the substrate, can yield great friction force because of a large true contact area. To elucidate the property of nanoscale friction, we measured the VA-CNT’s friction force. We used two types of VA-CNTs: grown Fe and Co as the catalysts. In the small normal force range, the coefficient of static friction was higher than that in the bigger force range. This result is different from the law of friction, which indicates that the coefficient of static friction force is constant. Moreover, The Fe-catalyzed-CNTs yielded greater friction force than the Co-catalyzed-CNTs did. This can be explained by the morphology and crystallinity of those CNTs. Because the Fe-catalyzed-CNTs can contact the substrate surface closely, they can cause greater friction force.</p>
