Synthesis, Morphology and Hydrophobicity of Core-Shell Fluoinated Copolymer Latexes

Abstract:

The fluoroacrylate copolymer latexes (Poly (BA-MMA-DFMA) latex) with a fluorinated shell were successfully synthesized by semi-continuous seeded emulsion polymerization. The chemical structure of the latex was characterized by Fourier transform infrared (FTIR) and 1H-NMR analysis. Glass transition temperatures (Tg) of Poly (BA-MMA-DFMA) latex were confirmed by DSC analysis. Transmission electron microscopy (TEM) showed the microstructure of Poly (BA-MMA-DFMA) latex. The water absorption ratio and the water contact angle (WCA) of films were studied. Results showed the Poly (BA-MMA-DFMA) latex had two distinct Tg and exhibited core-shell structure. Moreover, Poly (BA-MMA-DFMA) film with 15wt% DFMA can exhibit lower water absorption ratio and higher contact angle.
