| 摘要: |
A new bridged silsesquioxane (BSQ) was synthesized with isophorone diisocyanate (IPDI) and 3-
aminopropyltriethoxysilane (APTES). Highly cross-linked bridged polysilsesquioxane (BPSQ) sol was
prepared by the sol–gel polycondensation of the as-synthesized BSQ under basic catalysis. Transparent
film was obtained by dip-coating the BPSQ sol on the nickel sulfate hexhydrate (NSH, NiSO4·6H2O) crystal
wafer, an important kind of UV light filter used at wavelength 300 nm. The obtained BPSQ film was
nonporous (pore volume is 2×10−3 cm3 g−1) and exhibited very high condensation degree of siloxane
(99.0%). This film showed high optical transmittance and excellent moisture-resistant protection to the
NSH filter. Moreover, the thermal stability of the NSH filter was also greatly improved by the as-prepared
BPSQ film. |
