Synthesis and Characterization of Polyacrylate Latex Containing Fluorine and Silicon

Polyacrylate latex containing fluorine and silicon was successfully synthesized by semi-continuous seed emulsion polymerization, using organic silicon(OSi) monomer, fluorocarbon(FC), methacrylic acid(MAA), and butyl acrylate(BA) as raw materials. Transmission electron microscope(TEM) characterization indicated that the latex particles were form uniform analogous core-shell structure. Dynamic light scattering(DLS) show a narrow size distribution. The results of X-ray photoelectron spectroscopy(XPS) revealed the fluorine and silicon transfer to the film-air interface. The reaction was evaluated using fourier transform infrared(FT-IR) spectrum. The thermal stability of the latex films which analysed by thermogravimetric(TG) was improved due to the join of OSi and FC.
