Effects of CNT Composite on Snow Sliding Property and Water Sliding Property on the Vibrated Surface of Silicone/CNT Composite Sheets

摘要

The lotus leaf has unique property of holding water on its surface without penetrating inside the leaf.This phenomenon is technically termed Lotus Effect or super-hydrophobicity.Super-hydrophobic surfaces are used not only for resisting water and condensation,but also for preventing contamination.Various devices with super-hydrophobic surface are developed.Super-hydrophobic surface can be produced using various methods such as sol-gel processing and chemical vapor deposition method By these methods,it is difficult to produce hydrophobic surface in large-scale at low cost.Vapor grown carbon fiber(VGCF)is a new class of carbon fiber,which is distinct from other types of carbon fibers in its method of production.VGCF is of great scientific interest because of its excellent mechanical properties and electrical conductivity5’.Micro imprint performance of VGCF/polymer composites are examined and good transcription performance was achieved7-1.And,studies on super-hydrophobic sheets by micro imprint methods were reported.Then,low drag on VGCF/polymer composites surfaces was reported10).Vibration has been used to accelerate the velocity of water sliding on a silicone sheet.So far,studies on velocity of snow sliding on silicone sheet were limited.If vibration has an effect on snow sliding on a silicone sheet surface,prevention of accidents caused by falling snow was expected.The aim of the present study was to investigate snow sliding property on the vibrated silicone sheet and the vibrated CNT composite sheet.
