英文摘要: Abstract(#br)Poly(ionic liquid)s brush-grafted carbon dots (CDs-PILs-X) were synthesized for the first time by surface-initiated atom transfer radical polymerization, where X representing polymerization time was 1, 3, 6, 12, and 18 h. Their tribological properties as lubricant additives of polyethylene glycol (PEG200) were evaluated under the steel/steel contact and linear reciprocating mode. The CDs-PILs-1 exhibited the best friction-reducing and antiwear performance at a concentration ( c ) of 1.5 wt%. Specifically, the friction coefficient and wear volume of PEG200 were reduced by 61.9% and 82.5%, respectively. At a concentration ( c ) of 1.5 wt%, the performance of CDs-PILs-1 apparently outperformed that of PILs-1, reflecting the particularly important role of carbon cores in boundary...
