摘要： A film suitable for use as a light-modulating unit of a suspended particle device light valve. The film comprises a matrix polymer and has droplets of a liquid light valve suspension comprising a plurality of particles dispersed in a liquid suspending medium distributed within the matrix. The suspending medium (a) is substantially immiscible with the matrix polymer, (b) has a boiling point at atmospheric pressure greater than about 100 °C, (c) has an electrical resistivity of at least about 0.8 x 10 6 ohms per square, and (d) has an index of refraction at 25 °C which differs from that of the matrix polymer, measured at substantially the same temperature, by no more than about 0.002. The suspending medium comprises at least one liquid component selected from the group consisting of methyl pyrrolidinone, ethyl pyrrolidinone, dimethyl malonate, diethyl malonate, dimethyl succinate, di(propylene glycol)methyl ether, dimethyl phthalate, butyl phthalyl butyl glycolate, ethyl lactate, propylene carbonate, dimethyl perfluorosuberate, dimethyl tetrafluorosucciate, tetra (ethylene glycol)dimethyl ether, tri(ethylene glycol)dimethyl ether, di(ethylene glycol)dimethyl ether, ethylene glycol phenyl ether, epoxidized linseed oil, epoxidized soy oil, diethylisophthalate, a silicone copolyol-based laurate ester, a silicone copolyol copolymer, a silicone copolyol ester, a silicone copolyol-based isostearate ester, a silicone copolyol-based pelargonate ester diethylisophthalate, dimethyl octofluoroadipate, as well as mixtures thereof, and optionally one or more previously known liquid suspending media. The matrix polymer may optionally be cross-linked informing the film to produce a cross-linked polymer matrix.
