Materials with good microtribological properties are very important for microtribological research. A method was developed to synthesize surface modified C 60 molecule. The resulting C 60 styrene was analyzed with different analytical instruments. The LB (Langmuar and Blodgett) film technique was used to prepare the thin films. The tribological properties of the composite materials were tested. Results verify that the designed product could be produced, and it may be a new lubrication material.
