The copolymer was obtained as a brown solid. The structure of copolymer was characterized by UV and FTIR. GPC analyses shows that its average molecular weight Mw is 13 000. The copolymer is soluble in THF, DMSO and water. The surface tension of 0.5% of copolymer aqueous solution was determined to be 54.6×10-3 N/m（20 ℃）. TEM analyses shows that the copolymer is a kind of water-soluble nanosphere with the average diameter of about 60 nm.展开更多

It is soluble in water and of spherical shape with an average diameter of about 83 nm. As an additive for a base stock (a triethanolamine solution of mass fraction 2%), the fullerene copolymer was able to raise load carrying capacity and reduce the friction coeffient considerably.展开更多
