Lubricating Characteristic of Grease Composites with CNT Additive

The friction at high speed and high pressure tends to cause the lowering of grease stickiness because the frictional heating occurs at the sliding surface, which will bring to the degradation of lubricity. In order to improve the lubricity, carbon nanotubes (CNTs), which has excellent heat conductiv...
