Outline of Final Research Achievements

Disasters caused by snow and ice are frequent occurrence every year in winter. As a technology to prevent the disasters, ultra-low-drag hydrophobic CNT composite sheet using ultrasonic vibration is developed. An aim of this study is clarified with the effect of ultrasonic vibration on CNT composite sheet in water sliding, and is verified with the sliding performance of snow of CNT composite sheet under the influence of ultrasonic vibration. The variations of amplitude and frequency with the drag property of water droplets and snow particles on CNT composite sheets were clarified and discussed.
