Abstract
The thin films of C60 fullerenes were investigated as a coating material in surface finishing applications. The films were coated by vacuum evaporation on glass and silicon substrates. These films were annealed in oxygen ambient and exposed to a oxygen plasma. The C60 films coated substrates were also kept immersed in water and NaOH for a long time and tested for mechanical and optical properties. It was found that the optical properties and bulk properties were stable or modified favorably for surface finishing applications during these treatments. Though low temperature heating resulted in densification of C60 films, higher temperature above 300°C resulted in graphitization in oxygen ambient. These findings indicated that the thin films of C60 can be used as a corrosion resistive coating and UV cutting surface material below 300°C.
