摘要
采用细乳液聚合法制备了包有纳米炭黑颗粒（SiO2 修饰）和分散剂（四氯乙烯和Span80的混合液）的双相核材料的电子墨水纳米胶囊.通过细乳液聚合法制备了粒径在142-1106nm 之间的纳米胶囊.研究了SiO2 修饰对纳米炭黑颗粒表面电荷及粒径的影响,及修饰后的炭黑颗粒在直流电场下的响应行为.此外,研究了SDS及PVA 用量对纳米胶囊粒径的影响.
In this paper,two-phase electronic ink nanocapsules with carbon black nanoparticles modified by SiO2 as dispersant phase and the mixture of tetrachloroethylence and SPAN-80 as dispersant agent were obtained via miniemulsion polymerization.The obtained nanocapsule particle sizes were in the region of about 142-1 106 nm. We investigated the effects of SiO2 modification on the particle sizes and zeta potential change of carbon black nanoparticles.Meanwhile,the behaviors of the modified carbon black particles under direct current electric field were also studied.In addition,the influences of the amount of SDS and PVA on the particle sizes of nanocap-sules were investigated,respectively.
