    • PURPOSE: A carbon sphere having an even particle shape and narrow distribution and a use method thereof are provided to obtain the carbon sphere having excellent dispersibility and bistability during polymeric coating and a high charge through charge adjustment as a paint article for electronic paper display. CONSTITUTION: 27g of glucose and 100ml of distilled water are stirred in a beaker. A gas injecting unit injects nitrogen into a reactor for 5 minutes after the stirred liquid is put into the reactor. The temperature of the reactor is increased to 160°C by an external heat source and the temperature is maintained for 7 hours. An outcome is dried in an oven for 24 hours after the centrifugation of the liquid. A ball grinder grinds the dried outcome.
    • 目的:提供具有均匀粒子形状和分布均匀的碳球及其使用方法,以获得在聚合物涂层中具有优异的分散性和双稳性的碳球,以及通过电荷调节的高电荷作为电子纸显示用涂料。 构成:将27g葡萄糖和100ml蒸馏水在烧杯中搅拌。 气体注入单元将搅拌的液体放入反应器之后,将氮气注入反应器中5分钟。 通过外部热源将反应器的温度升高至160℃,并保持7小时。 将结果在离心液体后在烘箱中干燥24小时。 球磨机研磨干燥的结果。
