Carbon Dot-Based Nanofluids as Additives for Mechanical Lubrication

Xuan Li,
Baogang Wang,
Shanshan Dai
et al.

Abstract: The practical application of carbon dots (CDs) as lubricant additives was tremendously restrained by their complex and time-consuming preparation, separation, purification, and modification procedures. Here, the CD-based nanofluid was in situ prepared by pyrolyzing a deep eutectic solvent for 6 h under 180 °C and directly applied as a versatile lubricant additive of polyethylene glycol (PEG200) and polyalphaolefin (PAO4). At an optimum loading concentration of 3 wt %, the nanofluid distinctly improved the fric… Show more
