Self-stratifying polyacrylate latex containing silicon was synthesized via semi-continuous emulsion polymerization, using organic silicon and acrylate as raw materials. Transmission electron microscope(TEM) characterization indicated that the particles were form uniform analogous core-shell structure and dynamic light scattering(DLS) analysis possessed narrow size distributions. The results of X-ray photoelectron spectroscopy(XPS) proved the propensity of silicon enrichment at film-air interface, which revealed self-stratifying phenomenon. The thermal stability of the latex films determined by thermogravimetric analysis(TGA) was increased 24 °C as the join of organic silicon.
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.
