酞菁绿G／十八胺电泳液微胶囊制备与表征

Preparation and Characterization of Pigment Phthalocyanine Green G/Octadecylamine Electrophoretic Ink Microcapsule 1 2 ~TT^T~ r＇~. .1 1

试验在采用十八胺（ODA）（C17H35CH2NH2）化学修饰酞菁绿，并制备了稳定性良好的电泳液基础上，以此电泳液为囊芯，通过尿素和甲醛单体进行缩聚反应合成囊壁，制备绿色电子墨水微胶囊。采用光学显微技术（OM）和电镜技术（SEM）表征该电子墨水微胶囊，微胶囊呈现球形，表面光滑，平均粒径为91μm，包覆率达81％，在电场作用下具有明显的可逆移动。

This investigation takes pigment phthalocynine green G modified with octadcylamine （ODA） to prepare electro- phoretic liquid which shows good stability. Using urea -formal -dehyde （UF） as wall material, microcapsules containing the elec- trophoretic liquid are prepared by in situ polymerization. OM and SEM have been applied to eharacterize the morphology of the mi- erocapsule. The microcapsule is spherical and smooth with a size of 91 μm for the particle diameters and an encapsulation rate of 81%. The green electronic ink mierocapsule has a clear eleetrophoretic response.
