摘要Silica nanoparticles synthesized from tetraethoxysiliane (TEOS) via a solgel process were
surface-modified by using 3-(trimethoxysilyl)propyl methacrylate (MSMA) and 1H, 1H, 2H, 2Hperfluorooctyltriethoxysilane
(13F). MSMA acted as a coupling agent and a C=C provider, whereas
13F was employed to enhance hydrophobicity. The surface-modified silica particles together with a
multi-functional monomer were UV-cured to yield highly transparent thin films (~7 m) on plastic
substrates. Both FE-SEM imaging and UVvisible spectroscopy confirmed uniform dispersion of
nano-silica in the hybrid thin films. The coating surfaces were extremely smooth, with average
roughness over the range 1.02.3 nm based on profilometric measurements. X-ray photoelectron
spectroscopy indicated that surface-modified silica particles have migrated to the top surface to reduce
the surface energy. Therefore, only a small dosage of 1 mol% (vs. TEOS) was enough to engender
surface hydrophobicity with water contact angle of 100. Furthermore, all of the prepared coatings
were hard with pencil hardness reached 6H, and they adhered strongly to the poly(methyl
methacrylate) substrate according to the peel test.
