Abstract
A film suitable for use as the light-modulating element of an SPD light valve. The film comprises a cross-linked polymer matrix and has droplets of a liquid light valve suspension distributed in the cross-linked polymer matrix. The liquid light valve suspension comprises particles suspended in a liquid suspending medium, wherein the polymer matrix includes at least one siloxane co-polymer comprised of one or more of each of the following units, The film exhibits a greater degree of adhesion to substrates it contacts than films which do not include a unit as recited in (c) above. Additional embodiments include a suspended particle device incorporating the film as a light modulating element, as well as a method of preparing the film according to the invention.
