Abstract
Phthalocyanine green G modified with hyperdispersants was dispersed in tetrachloroethylene. Dispersibility and zeta potential of modified phthalocyanine green G in tetrachloroethylene were studied. The phthalocyanine green G particles modified with hyperdispersants were characterized by FTIR and SEM. E‐Ink containing dispersion liquid of phthalocyanine and tetrachloroethylene was prepared by coacervation, in situ polymerization, and interfacial polymerization. E‐Ink prepared by coacervation and in situ polymerization had a reversible electric response.
