    摘要: Porous polymer microspheres having a size of from about 3 to about 50 microns and a geometric standard deviation of about 1.25 or less are disclosed. The porous polymer microspheres are made by a method including the steps of preparing an emulsion comprised of polymer particles having an average particle size of less than about 3 microns and a diluent, subjecting the emulsion to an aggregating condition to form aggregated polymer particles, optionally coalescing the aggregated polymer particles, and removing the diluent to form the porous polymer microspheres.

    摘要: A method for displaying an image with an electrophoretic display device that includes a multiplicity of individual reservoirs, each containing an electrophoretic display fluid, located between two conductive film substrates, at least one of which is transparent, includes appropriately applying an electric field and a magnetic force to a selected individual reservoir in a manner to cause either a first set of particles or a second set of particles of the display fluid to be displayed. The first set of particles exhibit a color different from and contrasting to a color of the second set of particles, and also preferably a different charging property.
