The customer has published an article on the strategy of achieving macroscopic superlubricity by using this graphene oxide quantum dot as a nanoadditive in ethylene glycol aqueous solution. Realizing super lubrication only takes 6 seconds, which is 95.7% shorter than electric lubrication and reduces wear by 90.0%. Lubrication of EG solution with GOQDs as nano additives can achieve superlubricity under high contact pressure of 518.08 MPa in a mixed lubrication state. The adsorbed GOQDs in the friction film have a significant impact on the achievement of superlubricity due to the interlayer shear and rolling effects of boundary lubrication, as well as the enhanced load-bearing capacity. In addition, the friction force at low slip speeds can be significantly reduced by up to 58.8%. These findings can help develop new lubricating oils for industrial applications.
