A method of preparing a film suitable for use as a light-modulating element of a suspended particle device light valve, said method comprising: (i) preparing a quantity of a polymer matrix material, wherein the polymer matrix includes at least one siloxane co-polymer comprised of one or more of each of the following units, (a) at least one selected from the group consisting of a silicon-containing, non cross-linkable monomer, a silicon-containing non cross-linkable oligomer and a combination of both said monomer and said oligomer; (b) at least one silicon-containing cross-linkable monomer; and (c) at least one silicon-containing monomer having a non-cross-linking pendent moiety comprising one unhindered polar group capable of bonding to a substrate, wherein the polar group does not prevent the matrix polymer as a whole from being cross-linked, wherein said unit (c) incorporates, on two sides of a silicon atom therein, one selected from the group consisting of (a) two hydroxy groups, (b) two hydrolyzable alkoxy groups, and (c) a hydroxy group and a hydrolyzable alkoxy group, said incorporated groups being attached directly to the silicon atom, wherein the unit further includes an additional group attached to said silicon atom which is sufficient to satisfy the valance of the silicon atom, and wherein said additional unhindered polar group in said unit (c) comprises a functionality selected from the group consisting of acid and epoxy functionalities, (ii) forming an emulsion from the combination of at least a portion of the polymer matrix material and a quantity of a liquid light valve suspension, said suspension comprising a plurality of particles suspended in a liquid light valve suspending medium; and (iii) cross-linking the polymer matrix to substantially solidify the matrix polymer and produce a film having droplets of the liquid light valve suspension distributed in the cross-linked polymer matrix, wherein said cross-linking is carried out by exposing said matrix polymer emulsion to a sufficient amount of a form of energy selected from the group consisting of heat, UV radiation and electron-beam radiation to substantially convert said emulsion to a film, wherein the film exhibits a greater degree of adhesion to substrates in contact therewith than films which do not include a unit in (c) above. (i) preparing a quantity of a polymer matrix material, wherein the polymer matrix includes at least one siloxane co-polymer comprised of one or more of each of the following units, (a) at least one selected from the group consisting of a silicon-containing, non cross-linkable monomer, a silicon-containing non cross-linkable oligomer and a combination of both said monomer and said oligomer; (b) at least one silicon-containing cross-linkable monomer; and (c) at least one silicon-containing monomer having a non-cross-linking pendent moiety comprising one unhindered polar group capable of bonding to a substrate, wherein the polar group does not prevent the matrix polymer as a whole from being cross-linked, wherein said unit (c) incorporates, on two sides of a silicon atom therein, one selected from the group consisting of (a) two hydroxy groups, (b) two hydrolyzable alkoxy groups, and (c) a hydroxy group and a hydrolyzable alkoxy group, said incorporated groups being attached directly to the silicon atom, wherein the unit further includes an additional group attached to said silicon atom which is sufficient to satisfy the valance of the silicon atom, and wherein said additional unhindered polar group in said unit (c) comprises a functionality selected from the group consisting of acid and epoxy functionalities, (a) at least one selected from the group consisting of a silicon-containing, non cross-linkable monomer, a silicon-containing non cross-linkable oligomer and a combination of both said monomer and said oligomer; (b) at least one silicon-containing cross-linkable monomer; and (c) at least one silicon-containing monomer having a non-cross-linking pendent moiety comprising one unhindered polar group capable of bonding to a substrate, wherein the polar group does not prevent the matrix polymer as a whole from being cross-linked, wherein said unit (c) incorporates, on two sides of a silicon atom therein, one selected from the group consisting of (a) two hydroxy groups, (b) two hydrolyzable alkoxy groups, and (c) a hydroxy group and a hydrolyzable alkoxy group, said incorporated groups being attached directly to the silicon atom, wherein the unit further includes an additional group attached to said silicon atom which is sufficient to satisfy the valance of the silicon atom, and wherein said additional unhindered polar group in said unit (c) comprises a functionality selected from the group consisting of acid and epoxy functionalities, (ii) forming an emulsion from the combination of at least a portion of the polymer matrix material and a quantity of a liquid light valve suspension, said suspension comprising a plurality of particles suspended in a liquid light valve suspending medium; and (iii) cross-linking the polymer matrix to substantially solidify the matrix polymer and produce a film having droplets of the liquid light valve suspension distributed in the cross-linked polymer matrix, wherein said cross-linking is carried out by exposing said matrix polymer emulsion to a sufficient amount of a form of energy selected from the group consisting of heat, UV radiation and electron-beam radiation to substantially convert said emulsion to a film, wherein the film exhibits a greater degree of adhesion to substrates in contact therewith than films which do not include a unit in (c) above.
