Abstract:

Onion-like fullerenes (OLFs) were prepared by the chemical vapor deposition(CVD) method and purified by sulfuric acid and nitric acid treatment. The surface modification of OLFs was achieved by refluxing OLFs with stearic acid (SA). The dispersion capability and stability of SA coated OLFs as a lubricant additive was also investigated. Their morphology and structure were characterized by HRTEM. Fourier transfer infrared(FT-IR) spectrum also indicated that lots of functional groups existed on the surface of purified OLFs and the surface of OLFs was coated with a modified layer of SA. The dispersion capability and stability of SA coated OLFs as a lubricant additive were effectively improved.

Key words: onion-like fullerenes, chemical vapor deposition, lubricant additive, reaction mechanism
