Voltage switchable surface-modified carbon black nanoparticles for dual-particle electrophoretic displays

Carbon black/octadecane composites for room temperature electrical and thermal regulation

“…1(e), and new peaks appeared at 287.5 and 288.3 eV. The new peaks should come from the carbonyl and ester groups after hydroxyl groups reacted with oleic acid [27,30]. The similar structures of the function groups and hexane make CB-OA hydrophobic again but disperse well in hexane after 2 days of standing, as insert photo in Fig.…”

“…It has been proved to be a more effective method than the physical absorption of surfactants [27]. The surface structure of CB particles was characterized by XPS, as shown in Fig.…”

“…The CB particles were functionalized by the method reported by Kim et al [27]. Typically, 3 g of CB particles was dispersed in 300 mL of CH 2 Cl 2 in a flask by the help of an ultrasonic probe (750 W).…”

Preparation of black pigment with the Couette–Taylor vortex for electrophoretic displays

“…EPDs have been intensively researched because of their advantages: high contrast, wide viewing angle, less eye fatigue, low power consumption, and excellent flexibility (Bert et al, 2006;Chen et al, 2003;Chung and Jean, 2007;Comiskey et al, 1998;Kim et al, 2005Kim et al, , 2014Lee et al, 2013;Oh et al, 2009;Park et al, 2013;Sim et al, 2012;Sun et al, 2013;Yin et al, 2011;Zhao et al, 2011). EPDs basically consist of two parallel electrodes, a dielectric fluid, and two charged pigments which are white and black.…”

Mobility of black pigments for electrophoretic display depending on the characteristics of carbon sphere

“…Carbon-based materials such as carbon black [7,8], carbon sphere [9,10], and iron oxide-carbon composite [11,12] have been researched for creating a black color on displays. Carbon black is the most common black pigment in the application of EPD, which is attributed to reflectivity, thermal stability, chemical inertness, and availability.…”
