摘要：

This paper presents a kind of red encapsulated electronic ink prepared by in situ polymerization utilizing urea and formaldehyde as wall materials. Pigment scarlet powders with bright tone, small size and low special gravity were modified with polyethylene (PE) to have superior affinity for tetrachloroethylene. The modifying pigments were characterized by IR spectrometry and microphotography, and the microcapsules were also investigated in the same way. Experiments revealed that the pigments in the microcapsule moved toward negative electrode, while the field revised the pigments were pulled back reversible. And the response time of the particles was approximately 3.2 s. (C) 2004 Elsevier B.V. All rights reserved.
