Electrophoretic response of poly(methyl methacrylate) coated TiO2 nanoparticles

Surface modification of organic pigment particles for microencapsulated electrophoretic displays

“…White electrophoretic slurry (0.1 M) containing TiO 2 /PMMA composite particles (made in our laboratory) [13,14] was also prepared by ball milling. Yellowewhite or redewhite or bluee white electrophoretic fluid of dual-particle system was obtained by mixing two kinds of electrophoretic fluid and ultrasoniclly dispersing for 0.5 h. The electrophoretic slurry volume ratio of yellow/white, red/white and blue/white was set at 1/1, 1/10 and 1/2, respectively.…”

Slightly surface-functionalized polystyrene microspheres prepared via Pickering emulsion polymerization using for electrophoretic displays

“…The commonly used method currently is to encapsule the microspheres to prevent them from a large-scale flocculation [23,[27][28][29][30]. However, in the recent years, people try to disperse microspheres directly into the surfactant-containing apolar solvent to assemble the E-ink device [31][32][33][34], and in this situation the colloidal stability becomes much more important.…”

“…The property of the device is affected basically by the colloidal stability in the apolar solvent [25,26] and the electrophoretic mobility of the particles [26]. Because a stable colloid is not easy to be achieved in the apolar solvent, microencapsulation of the electrophoretic particles has been one of the most popular methods to produce the E-ink device, which can prevent the particles from a large-scale flocculation [23,[27][28][29][30]. Some electronic ink displays have been successfully produced via the microencapsulation process [18,23].…”

Preparation of titanium dioxide nanoparticles modified with methacrylate and their electrophoretic properties

“…Although titanium dioxide nanoparticles has the advantages of high whiteness and light refractive, it is very easy to aggregate due to the large density of particle and the strong interaction force between particles and electrode, resulting in an intense impact on the electrophoretic display response time and contrast ratio [7][8][9]. Some researchers use polymers to modify the surface of particles in order to improve the stability of titanium dioxide nanoparticles dispersed in the medium.…”
