Surface Reforming of Diamond Powder Using Silane Coupling Reagents

Abstract

Diamond surface reforming was performed using silane coupling reagents. Oxidation reaction with inorganic acid was utilized as the pretreatment of the diamond substrate. After the silane coupling reaction process, new peaks assigned to the silane coupling reagent appeared in the IR spectra. Moreover, the diamond surface property changed from hydrophilic to hydrophobic with the treatment of n-octyltrimethoxysilane. From the results of this study, it was confirmed that silane coupling reagents are effective for diamond surface reforming.
