Cold plasma functionalization of nanodiamond particles

Functionalization of three different types of detonation nanodiamonds was performed using a cold plasma discharge generated with fluorine containing gas. The chemical bonds formed between the reactive species generated in the plasma and nanodiamond particle surfaces were confirmed by FTIR and XPS analysis. From results of FTIR and XPS characterization, it was concluded that initial type of nanodiamond has little overall effect on the degree of fluorination. Fluorination of nanodiamonds allowed for the previously unavailable colloidal suspension in anisole. (c) 2006 Elsevier B.V. All rights reserved.
