Embodiment I

[0217] Prepared in glass ampoules containing dissolved in 70.35 x 10 -2 g (10.87%mol) tetraethoxysilane (TEOS) and 145.00×10 -2 1.1×10 in a mixture of g (64.59% mol) acrylic acid (AA) -3 g (0.13%mol) benzoyl peroxide (BP) and 74.50×10 -2 g (24.41% mol) of maleic anhydride (MAN) and then seal the ampoule in air. The inner surface of the ampoule was prehydrophobized by treatment with a 10% solution of dichlorodimethylsilane (DCDMS) in dry decane. After stirring the reaction mixture in the vessel using a shaker at ambient temperature for 30 minutes, the solution was heated in an oven according to the following temperature-time schedule:

[0218] 40→50℃ - 36h

[0219] 60℃ - 15h

[0220] 80℃ - 15h

[0221] 100℃ - 10h

[0222] 120℃ - 12h

[0223] 150℃ - 1h

[0224] The weight yield of the white opaque solid organic-inorganic nanocomposite article was equal to 93.5%. The physical properties of the organic-inorganic nanocomposites measured according to the test methods defin...

The inner surface of the ampoule was prehydrophobized by treatment with a solution of dichlorodimethylsilane (DCDMS) in dry decane. After stirring the reaction mixture in the vessel using a shaker at ambient temperature for 30 minutes, the solution was heated in an oven according to the following temperature-time schedule:

[0229] 40→50℃ - 27h

[0230] 60℃ - 18h

[0231] 80℃ - 8h

[0232] 100℃ - 18h

[0233] 120℃ - 20h

[0234] 150℃ - 1h

[0235] The weight yield of the white opaque solid organic-inorganic nanocomposite article is equal to 99.7%. The physical properties of the organic-inorganic nanocomposites measured according to the test methods def...

Embodiment III

[0239] Prepared in glass ampoules containing dissolved in 93.40 x 10 -2 g (12.59%mol) tetraethoxysilane (TEOS), 207.32×10 -2 g (37.81% mol) methacrylic anhydride (MAAN), 98.30 × 1 -2 g (38.35%mol) acrylic acid (AA) and 78.15×10 -2 15.2×10 in a mixture of g (11.08% mol) ethylene glycol dimethacrylate (DMEG) -3 g (0.17% mol) of benzoyl peroxide (BP) solution, the ampoule is sealed in air. The inner surface of the ampoule was prehydrophobized by treatment with a solution of dichlorodimethylsilane (DCDMS) in dry decane. After stirring the reaction mixture in the vessel using a shaker at ambient temperature for 30 minutes, the solution was heated in an oven according to the following temperature-time schedule:

[0240] 40→50℃ - 75h

Description

[0001] Cross References to Related Applications [0002] This application hereby claims priority under 35 U.S.C. $119(e) to U.S. Provisional Patent Application No. 60 / 866,497, filed November 20, 2006, which is hereby incorporated by reference. field of invention [0003] The present invention relates to composite materials comprising organic and inorganic interpenetrating polymer networks. Background technique [0004] Organic-inorganic composites are becoming increasingly important because of their special properties arising from the synergy between organic and inorganic components and properties of interfacial regions. The great possibility of different combinations between organic and inorganic substances enables the fabrication of nanocomposites in different morphologies with unique properties not obtainable by conventional composites. [0005] A key challenge in the design of such organic-inorganic systems lies in controlling the mixing between the two different substa...
