摘要

Electronic inks are disclosed herein. One embodiment of the electronic ink includes a non-polar carrier fluid, a plurality of negatively charged colorant particles (10, 20) dispersed in the non-polar carrier fluid, a small molecular additive (MA), and a charge director. Each of the negatively charged colorant particles (10, 20) includes a surface modified with an acidic functional group (AFG). The small molecular additive (MA) has at least two branches, each of which includes nitrogen or oxygen atoms.
