SPD LIGHT VALVE FILM INCORPORATING NEW SUSPENDING MEDIA, AND LIGHT VALVE INCORPORATING SAME |
摘要 |
<p>A film suitable for use as a light-modulating unit of a suspended particle device light valve, comprising a plurality of particles dispersed in a liquid suspending medium, distributed within an optionally crosslinked matrix polymer. The suspending medium is substantially immiscible with the matrix polymer, has a boiling point greater than about 100° C., has an electrical resistivity of at least about 0.8x10<SUP>6 </SUP>ohms per square, and has an in endex of refraction at 25° C. which differs from that of the matrix polymer by no more than about 0.002.</p> |
