Electrophoretic ink, electronic paper and display method for electronic paper

摘要

An embodiment of the invention discloses a kind of electrophoretic ink comprising an electrophoretic display solution which is an electrorheological fluid comprising a base solution, solid particles and an additive, wherein the solid particles account for 5%-50% of the electrorheological fluid by mass-volume percentage. The electrophoretic display solution is preferably a negative electrorheological fluid. The invention also discloses an electronic paper comprising the electrophoretic ink and a display method for the electronic paper.

主权项

1. Electrophoretic ink comprising an electrophoretic display solution which is a negative electrorheological fluid comprising a base solution, solid particles and an additive,
wherein the additives are selected from the group consisting of water, acids, alkali, salts and surfactants, wherein the solid polyamic acid salt particles account for 5% to 50% of the negative electrorheological fluid by mass-volume percentage, and wherein the negative electrorheological fluid is polyamic acid salt/silicone oil system.
