Relationship between CNT Orientation of Nanocarbon Fiber Silicone-matrix Composite Film and Sliding Property of Water Droplet

抄録

The surface of nanocarbon fiber silicone-matrix composites causes water droplets to be slippery with presence of CNTs (Carbon nanotube). However, the assistance of CNTs in decreasing the resistance of water droplets has not been clarified yet. It was confirmed that further increasing the amount of CNTs promotes fiber orientation on the surface. The aim of this research is to clarify the mechanism by which sliding property of water droplets of composites containing CNTs. In this paper, composites which have different orientations were created and their effects on the sliding property of water droplets are reported. A silicone resin solution containing CNTs was shaped by a bar coater while applying shear stress (called Film). CNTs on surfaces of the film were oriented. Water droplets on the film with higher degree of orientation tended to be slippery. This result means that fiber orientation on surfaces is related to the sliding property of water droplets. And it may help prediction of movement of droplets on surfaces.
