摘　　要：通过自由基聚合,合成了一种新型纳米级富勒烯-苯乙烯-丙烯酸三元共聚物,该聚合物易溶于碱性水、甲醇、四氢呋喃等溶剂。采用FTIR、UV-240等进行结构表征。TEM分析表明其在水溶液中形貌为理想的球形,平均粒径约为36nm。四球机试验测试结果表明,一定浓度的该富勒烯共聚物可有效增强抗磨能力。对其磨斑表面采用电子扫描显微镜分析,结果表明,磨痕变浅,磨斑减小,有效地降低了磨损。A novel fullerene - styrene - acrylic acid copolymer was synthesized via radical polymerization. It is soluble in polar solvents such as water, methanol, acetone, tetrahydrofuran. The product was characterized by FTIR.UV- Vis and GPC. TEM analysis shows that the average particle diameter is about 36nm. Four - ball tests shows that the addition of a certain concentration of the fullerene copolymer to base stock can effectively raise the load - carrying capacity (PB value), and raise the antiwear ability. SEM analysis shows that the additive results in reducing diameter of wear scar and decreasing wear.
