NOVELTY - Light valve with increased compressive strength, comprises a first transparent substrate, a first transparent electrode formed on the first transparent substrate, a second transparent substrate, a second transparent electrode formed on the second transparent substrate USE - Used as light valve with increased compressive strength. ADVANTAGE - The light valve: has excellent high temperature and pressure resistance; and can meet the requirements of the lamination process for the subsequent production of dimming glass components. DETAILED DESCRIPTION - Light valve with increased compressive strength, comprises a first transparent substrate, a first transparent electrode formed on the first transparent substrate, a second transparent substrate, a second transparent electrode formed on the second transparent substrate. The first transparent electrode and the second transparent electrode are disposed opposite to each other. A light control layer disposed between the first transparent electrode and the second transparent electrode; the light control layer includes a polymer matrix, where suspension medium droplets are dispersed in the polymer matrix, and solid light-controlling particles are distributed in the suspension medium droplets, the polymer matrix is obtained by crosslinking and curing at least one siloxane copolymer, and the siloxane copolymer is obtained by copolymerizing monomers including (a) silicon-containing non-crosslinking monomer, which may be provided in the form of silicon-containing non-crosslinking monomer and/or an oligomer, (b) silicon-containing crosslinkable monomer, and (c) silicon-containing monomer of formula (R-Xm-(CH2)n-SiR1xR2y) with high occupancy side chains. R1= hydroxy, -Cl or 1-3C alkoxy, preferably -OH, -Cl, -OCH3, -OCH2CH3, -OCH(CH3)2, -OCH2CH2OCH3, -O-C(=O)-CH3, more preferably -OH, -Cl, -OCH3or -OCH2CH3; R2= 1-3C alkyl, preferably methyl or ethyl; x, y = 0-3, preferably 2 or 3; x+y = 3; X = nitrogen, oxygen or sulfur; m = 0 or 1; n = 0-10, preferably 0, 1, 2 or 3, more preferably 2 or 3; R = non-polymeric group including H or chain or cyclic group R'; and R' = alkyl, cycloalkyl, aryl, heterocyclyl, cycloalkylalkyl, heterocyclylalkyl, aralkyl, carbonyl or carbamoyl (optionally substituted with hydroxy, amino, mercapto, acidic group, alkoxy, aryloxy, alkylthio, arylthio, alkylamino, arylamino, ester, halo or epoxy (optionally substituted)). INDEPENDENT CLAIMS are also included for: Dimming glass assembly comprising a first glass plate and a second glass plate, and a light valve as disposed between the first glass plate and the second glass plate; and method for improving pressure resistance of light valve, comprising providing light control layer matrix emulsion, and coating the light control layer matrix emulsion on the first transparent electrode to form light control layer wet film, covering the second transparent electrode on the light control layer wet film, and crosslinking and curing the wet film of the light control layer to obtain light valve, where the light control layer matrix emulsion contains a polymer matrix precursor, the polymer matrix precursor is dispersed with suspension medium droplets, and solid light control particles are distributed in the suspension medium droplets.
