Abstract:Red Pigment 48:2 (PR 48:2) was coated with polyethylene (PE). The chemical constitution of the modified pigments was identified by fourier transform infrared spectroscopy (FT-IR), transmission electron microscopy (TEM) and field-emission scanning electron microscopy (FE-SEM). The modified particles have good dispersity and high electrophoretic mobilities. For a simple EPD device, the contrast ratio of red-white electrophoretic fluid reached 2.60.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
