摘要Dye-grafted silica nanoparticles (GSiO2 ) were synthesized via a dual-step process involving, first, attachment of the organic dye Disperse Red 1 (DR1) to the coupling agent, 3-isocyanatopropyltri-
ethoxysilane, by means of urethane bonds, and then
grafting of the silylated-DR1 onto silica nanoparticles
(6 nm) prepared by hydrolysis and condensation of
tetraethoxysilane in a sol–gel process. Dye-adsorbed
silica nanoparticles (DSiO 2 ) were also prepared for
comparison, for which DR1 was bound only physically
to silica instead of covalent bonds. The thermal
behaviors of the formed GSiO 2 and DSiO 2 were
examined by means of differential scanning calorime-
try and thermal gravimetric analysis. The results
showed that both the particle size and silica content
have significant effects on the thermal behaviors of the
dye-adsorbed and dye-grafted silica. Moreover, crys-
talline DR1 lost significantly its crystallinity after being
adsorbed on silica, and became virtually amorphous
after being grafted onto silica. The formed particles
were UV-cured with a multifunctional acrylic mono-
mer to yield color coatings on glass substrates. UV–
visible spectra indicated that brightness and color
saturation of the coating comprising GSiO 2 could be
maintained better than that comprising DSiO 2 after
heat treatment at 280C.
