摘　　要：A novel fullerene-acrylamide copolymer was synthesized via radical polymerization. It is soluble in polar sol- vents such as water, dimethyl sulfoxide etc. The product was characterized by FTIR, UV-Vis and GPC. TEM analy- sis shows that the average particle diameter is about 46 nm. Four-ball tests show that the addition of a certain con- centration of the fullerene copolymer to base stock (2 wt% triethanolamine and 0.5 wt% OPZ aqueous solution) can effectively raise the load-carrying capacity (PB value) and the antiwear ability. SEM analysis shows that the addition results in reducing diameter of wear scar and decreasing wear.A novel fullerene-acrylamide copolymer was synthesized via radical polymerization.
