Abstract
An embodiment of the invention provides a method for forming microcapsules for electrophoresis display by forming microcapsules through a complex coacervation reaction between a sulfonated styrene maleic anhydride copolymer and gelatin, wherein a mass ratio of the sulfonated styrene maleic anhydride copolymer to the gelatin is 1:10˜10:1. The method of the embodiment of the invention not only can obtain microcapsules with good sealability and stability, but also can obtain microcapsules having evenly distributed particle sizes and low cost.
