| 摘 要： | 通过自由基聚合，合成了一种新型nm级富勒烯－衣康酸共聚物，它易溶于水，甲醇，丙酮，四氢呋喃等溶剂。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48nm。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提高水基液的承载能力，增强抗磨能力，对其磨斑表面采用电子扫描显著微分析，结果表明，磨痕斑减小，有效降低了磨损。

| Abstract: | A novel fullerene itaconic acid copolymer is synthesized via radical polymerization. It is solubled in polar solvents such as water, Methanol, Acetone, Tetrahydrofuran. The product is identified and characterized by FTIR, UV Vis, GPC. TEM analysis shows that it presents an ideal sperical shape in water with an average diameter of about 48?nm. Four ball tests show that the addition of a certain concentration of the Fullerene copolymer to base stock can effectively raise the load carrying capacity ( P B value), and raise the antiwear ability. JSM 35C model for scanning electron microscope(SEM) is used to examine the morphologies of the worn surfaces, which shows that the additive results in reducing diameter of wear scar and decreasing wear. |
