A method including: sonicating a stream containing a dispersion comprised of agglomerated primary particles; and filtering the resulting sonicated stream containing a dispersion comprised of de-agglomerated primary particles. An apparatus including: an ultrasonic adapter to ultrasonicate a stream of a liquid dispersion of agglomerated primary particles; and a filter member adapted to filter the resulting ultrasonicated stream containing a dispersion of de-agglomerated primary particles; and optionally a coater adapted to coat the resulting filtered stream containing a dispersion of de-agglomerated primary particles onto a receiver.

A coating process for the fabrication of organic photoreceptors employs an electrically conductive single slot die biased to allow an electric field between the die and the ground plane on the photoreceptor substrate. The homogenous coating dispersion is fed through the die at a predetermined gap and rate to control coating thickness at the same time that an electric field is applied. The formulation, rheology, particle mobility, coating speed, electric field and the like are controlled so that the photogenerator particles migrate to the substrate in the dwell time defined by the coating die region.

A manufacturing system including: (a) a vessel for holding a liquid; (b) a first member and a second member, each having a flat surface, wherein the flat surface of the first member faces and is spaced from the flat surface of the second member, thereby defining a gap region between the two flat surfaces, wherein a section of the first member is transparent through the thickness of the first member; (c) a liquid delivery system connected to the vessel and the gap region which delivers the liquid to the gap region and the liquid flows in the gap region in view of the transparent section of the first member; (d) a camera positioned to view through the transparent section of the first member; (e) image processing means coupled to the camera for determining the homogeneity of the liquid in the gap region; and (f) liquid dispensing equipment connected to the liquid delivery system.

A coating process including providing a coating composition comprising finely divided photoconductive organic particles dispersed in a solution of a film forming binder, the composition having a predetermined substantially constant liquid yield stress value, flowing the composition along a feed channel, introducing the composition into an elongated manifold cavity comprising a least a first progressively narrowing channel extending away from the feed channel, flowing the coating composition along at least the first progressively narrowing channel, flowing the coating composition out of the manifold cavity into an extrusion passageway extending away from at least the first progressively narrowing channel, shaping the coating composition into a thin ribbon shaped stream in the extrusion passageway, depositing the ribbon shaped stream on a substrate to form a coating, and maintaining an applied shear stress to the composition that is greater than the yield shear stress value of the coating composition while flowing the composition through the at least first progressively narrowing channel and extrusion passageway.

A method of forming one or more polymer containing layers on a substrate using ink jet nozzles. The method is particularly suited to forming one or more polymer containing layers of a photoreceptor. The polymer containing layers may be formed by moving a substrate, in particular a cylindrical substrate, past the ink jet nozzles, by moving the ink jet nozzles over the substrate, or both. The ink jet nozzles are capable of being independently controlled in order to permit precise location of the coating on the substrate.

A method for improving the quality of a dip coated layer that is deposited by flowing a solution along a substrate in a gap between the substrate and a wall, including: (a) determining a yield stress, a viscosity, a density, and a surface tension of the solution, and selecting a wet thickness of the coated layer; (b) determining a coating speed based on the determined viscosity, the determined density, the determined surface tension of the solution, and the selected wet layer thickness; and (c) selecting a distance for the gap and calculating the shear stress of the solution in the gap based on the gap distance, wherein the shear stress is greater than the yield stress.
