摘要Colloidal silica nanoparticles synthesized from tetraethoxysilane via a sol–gel process were
surface-modified first by 3-(trimethoxysilyl)propyl
methacrylate, and then by trimethylethoxysilane
(TMES). The former agent acts both as a coupling
agent and as a C=C provider, whereas the latter agent
is used to prevent particle aggregation and to increase
hydrophobicity of the coating. The modified silica
particles were UV-cured together with the monomer,
2-hydroxyethyl methacrylate (2-HEMA), and the
crosslinking agent, dipentaerythritol hexaacrylate
(DPHA), to form highly transparent hard coatings on
plastic (PMMA and PET) substrates. Both differential
scanning calorimetric and thermal gravimetric analyses
of the hybrid materials indicated enhanced thermal
stability with respect to the neat HEMA–DPHA
copolymer. Furthermore, due to the incorporation of
TMES, hydrophobicity of the hybrid coating increased
considerably with increasing modified silica content. In
the extreme case, an antiabrasive hard coating (7H on
PMMA) with a water contact angle of 99 was obtained at the silica content of 15 wt%.
