A suspended particle device (SPD) film or laminate thereof. The film includes substrates coated on their inner surface with a polythiophene-based conductive polymer serving as electrode means. The polymer may be applied in the form of an aqueous composition also comprising solvent(s) and binder(s). A preferred polymer is a polyethylene dioxythiophene (PEDT) polymer. The polymer may be doped with polystyrene sulfonate. The polymer may be connected to a conductive material that extends beyond an outer boundary of the film to connect with a voltage source. Adhesive strength between the cured emulsion and the polymer is at least 1.46 N/25 mm. A further aspect constitutes a method for increasing adhesion between a cured suspended particle device emulsion and electrode means in a light valve film. The method comprises applying the polymer on an inner surface of the substrates constituting the film to serve as the electrode means.
A suspended particle device (SPD) film, said film comprising a pair of opposed, spaced apart cell walls, a cured emulsion between the cell walls, and electrode means located upon at least a portion of an interior surface of said cell walls, said cured emulsion having droplets of a liquid light valve suspension, with a plurality of particles dispersed in the liquid suspending medium, distributed within a cured polymer matrix material,
A method for increasing adhesion between a cured suspended particle device emulsion and electrode means in a suspended particle device (SPD) film, said film comprising a pair of spaced apart cell walls, a cured matrix polymer material between the cell walls and electrode means located upon at least a portion of an interior surface of said cell walls, said cured matrix polymer material having droplets of a liquid light valve suspension comprising a plurality of particles dispersed in the liquid suspending medium distributed within the matrix, wherein said method comprises:
