One-step cover closing method of electronic paper micro-cup and cover closing material

The invention relates to an electronic paper micro-cup, in particular to a method for the one-step sealing of the electronic paper micro-cup on flexible basal material in solvent with strong dissolution or swelling such as tetrachlorethylene, and sealing material thereof. According to the invention, unsaturated acrylic ester derivatives are taken as main material to prepare sealing glue liquor together with oligomers, monomers, a photoinitiator, a modifier, a surfactant and conductive material. The sealing glue liquor is mixed with pigment dispersing liquor according to certain proportion and is used for completing the sealing through emulsification and dispersion, delamination, and photo solidification. The sealing thickness can be accurately controlled through the volumetric ratio of the sealing glue liquor and the pigment dispersing liquor. The invention can not only be suitable for sealing electronic ink or liquid crystal to realize flexible or rigid plate display, but also be used for the micro-flow cont
