Abstract
A kind of electronic ink, which is supported on indium-tin-oxide (ITO) glass before polymerization, is prepared using urea and formaldehyde resin as wall materials, in which TiO2 modified with PMMA are dispersed in tetrachloroethylene (TCE) using a mixture of oil blue dyes and charge control additive (span80). Rotary viscometer, Fourier transform infrared spectroscopy (FT-IR) and optical microscopy are used to characterize the particles, respectively. The electrophoretic mobility of the microcapsules to electric field is also investigated with two parallel electrodes.
