Synthesis and characterization of fluorine-containing polyurethane-acrylate core-shell emulsion

摘要

Fluorinated polyurethane-acrylate (FPUA) hybrid emulsion was prepared by copolymerization of polyurethane, methyl methacrylate, and 1H,1H,2H,2H-heptadecafluorooctyl acrylate (FA) via emulsion polymerization in the presence of a perfluoronated reactive surfactant. The polyurethane was synthesized from isophorone diisocyanate, poly(propylene glycol)-1000, dimethylolpropionic acid, 1,4-butanediol, and 2-hydroxyethyl methylacrylate. The influence of the monomer on the surface properties, wetting behaviors, particle size, and viscosity of the emulsion was investigated. The mechanical properties of FPUA latex films were improved, and water absorption and contact angle were improved with the addition of methyl methacrylate and FA. (c) 2016 Wiley Periodicals, Inc. J.
