详细
The comparison of the formation processes of volatile products at heating mixtures of detonation nanodiamonds with perfluorochemical alcohol and nanodiamonds subjected to directed chemical modification with perfluorochemical alcohol was made using the thermodesorption mass-spectrometry. A change of the destruction mechanism and increase of the thermostability of perfluorochemical alcohol by ~ 100°C as a result of a directional chemical modification was revealed, the most possible models of functionalization through hydrogen and covalent bonds of the hydroxyl group of fluorine radicals with carboxyl groups of surfaces of nanodiamond particles are suggested, the degrees of the functionalization and energy of the desorption activation of the products of the destruction functionalized molecules are assessed.
