摘要
采用正交设计方法,以十八胺改性酞菁绿G形成电泳颗粒,以四氯乙烯和1,2-二溴乙烷的复配液为分散介质,Span-80和CH-6超分散剂为稳定剂,制备了分散性和稳定性良好的电泳显示液.采用红外光谱、偏光显微镜技术、粒径分布、紫外光谱和电泳实验,对绿色电子墨水电泳液的化学结构、分散稳定性、粒径分布和电场响应时间等性能进行表征.结果表明,经过化学修饰的酞菁绿G颗粒带负电荷,在分散介质中的分散性和稳定性良好,所制备的绿色电泳液在直流电场下有响应行为.
This investigation focuses on pigment phthalocynine green G modified with octadcylamine, which is suspended in tetrachloroethylene and 1,2-dibromoethane using span-80 and CH-6 hyperdispersants as emulsifiers. The suspending f/uid represents superior dispersibility and stability. The green suspension is measured for various properties, such as chemical structure, dispersing stability and electric field responsive time. Based on these factors, green electrophoretic ink is successfully prepared. Results show that the dispersibility and stability for the modified samples of pigment phthalocynine green G are improved in the dispersion medium. The green suspension has a significant response in the field of direct current, featured for negative charge particles in the system studied. Therefore, microcapsules with a core of green suspension and a wall of urea-formaldehyde polymer are synthesized.
