摘要：

The core-shell polyurethane-acrylate(PUA) emulsion containing fluorine and silicon in the core was synthesized by "one-pot" emulsion polymerization in the presence of castor oil-based polyurethane without traditional emulsifier, using methyl methacrylate (MMA), butyl acrylate (BA) as the main monomers, dodecafluoroheptyl methacrylate (G04), gamma-methacryloxy propyl trimethoxyl silane (KH-570) as the functional monomers. The structure and properties of the fluorinated-silicated PUA and their films were characterized by transmission electron microscopy (TEM), Fourier transform infrared spectrum (FT-IR) and contact angle testing. The results showed that fluorine and silicon monomers had effectively copolymerized with acrylic monomers and a core-shell structure in the latex was formed. The water contact angle for film-air interface is 92.5 degrees, and the cetane contact angle for film-air interface is 47.5 degrees.
