METHOD OF MANUFACTURING MICROCAPSULE FOR DISPLAY

摘要

The present invention provides a method of manufacturing a microcapsule having a uniform particle size, wherein microcapsules for displays, having a uniform particle size distribution, can be obtained by forming droplets using a porous membrane (membrane emulsification) and then encapsulating the droplets, differently from a conventional method that uses a homogenizer or an ultrasonic apparatus during an emulsification process for manufacturing a microcapsule for displays. The method includes the steps of: introducing a dispersed phase solution including a liquid crystal or electrophoretic material into a continuous phase solution including a surfactant by passing the dispersed phase solution through the pores of a membrane to prepare an oil-in-water emulsion in which droplets are formed; and encapsulating the droplets to form outer walls on the droplets.
