| 摘要: |
Three bridged silsesquioxanes were synthesized via the reactions between 3-aminopropyltriethoxysilane and
three different diisocyanates, i.e., m-xylylene diisocyanate, 1, 6-diisocyanatohexane, and isophorone diiocyanate.
The subsequent bridged polysilsesquioxane sols were prepared by the room-temperatured polycondensation of
these bridged silsesquioxane using basic catalysis. Transparent films with a thickness of around 330 nm were
obtained by dip-coating the bridgedpolysilsesquioxane sols on the nickel sulfate hexahydrate (NiSO4·6H2O,NSH)
crystal wafers that are commercially used as ultraviolet light filter working at a wavelength of 300 nm. The N2
adsorption/desorption experimental results showed that the films were all nonporous with pore volume less
than 2×10−3cm3 g−1. The obtained three polysilsesquioxanes all exhibited very high condensation degree of
siloxane (above 99%). These films showed high optical transmittance at desiredwavelengths (280–320 nm) and
excellent moisture-resistant protection to the NSH filters. |
