Abstract:
A moisture-resistant suspended particle device film comprising a cured suspended particle device emulsion having a plurality of uncrosslinked droplets of a liquid light valve suspension distributed throughout the cured emulsion; first and second glass or plastic sheets located outwardly from and sandwiching the cured emulsion, wherein located on an inner aspect of each sheet, adjacent the cured emulsion, is a thin, transparent, electrically conductive coating, the coating serving as an electrode to permit passage of an applied electric field through the cured emulsion; and a moisture-resistant barrier located around an entire outer peripheral edge portion of the film, wherein the barrier is comprised of a barrier material that eliminates or at least reduces passage of moisture from outside the film into the cured emulsion, thus preventing development of a light-frame pattern in the film that would otherwise be caused by the moisture. The disclosure also discloses forming a laminate comprising the above-described film, as well as methods of forming such films and laminates.
