Synthesis and Basic Properties of Fluorinated Core-Shell Acrylic Latexes Containing Perfluoroalkyl Acrylate in the Shell

Abstract

Fluoroacrylic copolymer latexes with core-shell structure were synthesized by free-radical emulsion copolymerization, using fluorine-containing acrylic monomer of dodecafluoroheptyl methacrylate (DFMA) and fluorine-free acrylic monomers. The chemical composition was characterized by Fourier transform infrared (FTIR) spectroscopy. The basic properties of the latexes including mainly hydrophobicity, chemical stability, chemicals-and corrosion-resistance were investigated. Significant improvement in the chemicals-and corrosion-resistance were observed for the fluorinated copolymer although only 5 wt% (based on the total monomers amount) of DFMA was copolymerized.
