Abstract
The dispersibility of diamond has been improved
by reforming its surface with 2-propanol-2-yl[(CH3)2C·
OH]
radicals. These radicals were produced by the photochemical
breakdown of 1-[4-(2-hydroxyethoxy)-phenyl]-2-hydroxy2-methyl-1-propane-1-one
(HPHMP) under ultraviolet (UV)
radiations. The diamond particles were mixed with HPHMP
in acetone and were placed under UV rays for the generation
of required free radicals which were in situ reformed the diamond
surface. Fourier transform infrared, nuclear magnetic
resonance spectroscopy and scanning electron microscopy
(SEM) confirmed the structural and surface reforming of diamond.
The thermogravimetric analysis, thermogravimetric
analysis–mass spectrometry spectrogram confirmed the surface
reforming of diamond with 2-propanol-2-yl radicals.
The dispersion behavior of the diamond after reforming was
observed by SEM analysis and revealed an improvement in
dispersibility in common solvents.
