多壁碳纳米管可以作为润滑脂添加剂。在低载荷下,多壁碳纳米管可以增加脲基润滑脂的润滑性,同时对工程塑料摩擦副也有良好的减摩作用。多壁碳纳米管的作用机理是形成了"滚珠效应"。
Multi-walled carbon nanotubes could be used as grease additive.Multi-walled carbon nanotubes could increase the lubricity of urea grease,and had a good friction reducing effect for engineering plastics frictional couple at low loads.The mechanism of multi-walled carbon nanotubes was the "ball effect" formed.
