Fluorination and characterization of nanodiamond particles. (South Carolina Junior Academy Of Sciences Abstracts).Diamonds and diamond-like carbon films have received much attention due to their great hardness, chemical inertness, optical transparency, and good field emission, among other properties. Fluorine fluorine (fl `ərēn, –rĭn), gaseous chemical element; symbol F; at. no. 9; at. wt. 18.998403; m.p. −219.6°C;; b.p. −188.14°C;; density 1. is often
reacted with carbon systems, especially carbon nanotubes, because it is
known to react with graphite to create graphite fluoride. We hope that
by fluorinating nanodiamonds in the same way as nanotubes they will
become more reactive. In the fluorination fluor·i·na·tion n. A chemical reaction that introduces fluorine into a compound. , elemental fluorine, diluted with helium, was passed through a temperature-controlled Monel[TM] flow reactor containing the nanodiamonds. The analysis of the fluorination included Fourier-transform infrared spectroscopy in the KBr pellet method, Energy Dispersive dispersive /dis·per·sive/ (-per´siv) 1. tending to become dispersed. 2. promoting dispersion. Fluorescent X-Ray Analysis (EDAX), and Scanning Electron Microscope scan·ning electron microscope n. Abbr. SEM An electron microscope that forms a three-dimensional image on a cathode-ray tube by moving a beam of focused electrons across an object and reading both the electrons scattered by the object and images. The analysis showed that significant amounts of fluorine could be added to nanodiamonds. Infrared showed the presence of covalently bound fluorine, confirmed by EDAX. The SEM showed that particle size decreased with longer times.
