    Abstract

    The reactivity of hydrogenated diamond surfaces with peroxide radical initiators such as benzoyl peroxide, lauroyl peroxide, dicumyl peroxide and di-t-butyl peroxide was investigated in this study. With benzoyl peroxide as the radical initiator, the intensity of the peaks assigned to the aliphatic C-H stretching vibration decreased with increasing reaction time, as well as with increasing amount of benzoyl peroxide. Moreover, peaks assigned to the aromatic C-H and C=O stretching vibrations appeared following the reaction. For the reaction with lauroyl peroxide, the area under the peaks assigned to the C-H bond increased with treatment time and amount of lauroyl peroxide, and a C=O stretching vibration peak appeared. The shape of the IR spectra of diamond powder treated with dicumyl peroxide or di-t-butyl peroxide is virtually the same as that of hydrogenated diamond powder surface.
