Study on Charge Mechanism of EPID Particles
Abstract:Electrophoretic polymer coated inorganic pigment were synthesized by using silane coupling agent and highly hydrophilic monomers. Silane coupling agents which have charge and polymerable functional group were used to modify particles and monomers which have more than eight carbon atoms were used to form polymer coating layer on particles by radical reaction. Silane coupling agent serve pigment with charge, and polymer layer reduces the specific density of pigment and prevent the pigment from flocculating in electrophoretic solvent. By choosing proper silane coupling agent and coating monomer, the charge polarity of particles can be control and the final polymer coated pigment show good stability, quick response and high reflectance in electrophoretic image display.

For more than 25 years, NIP has been the leading forum for discussion of advances and new directions in non-impact and digital printing technologies. A comprehensive, industry-wide conference, this meeting includes all aspects of the hardware, materials, software, images, and applications associated with digital printing systems, including drop-on-demand ink jet, wide format ink jet, desktop and continuous ink jet, toner-based electrophotographic printers, production digital printing systems, and thermal printing systems, as well as the engineering capability, optimization, and science involved in these fields.
Since 2005, NIP has been held in conjunction with the Digital Fabrication Conference.
