Synthesis and characterization of hybrid latexes from soybean oil-based polyurethane and poly(2,2,2-trifluoroethyl methacrylate)

Abstract

A class of novel fluorine containing core-shell hybrid latexes were obtained from soybean oil-based polyurethanes and poly(2,2,2-trifluoroethyl methacrylate) (PTFEMA) by two-step synthesis under mild reaction conditions. Structural and morphology properties of the resulting hybrid latexs have been characterized by FT-IR and TEM. In addition, thermal properties (DSC, TGA) and coating performance (contact angle, stress-strain curve, and surface free energy) were investigated and discussed. The hybrid latexes exhibit outstanding thermal stability and coating performance. More importantly, through this method, low-valued foods are successfully transformed into high-valued functional materials which bring new solutions for preparing materials from renewable sources.
