- Abstract
A core-shell fluorine-silicon modified polyacrylate hybrid latex was successfully prepared via emulsifier-free emulsion polymerization. The chemical composition and core-shell morphology of the resultant hybrid particles were investigated using 1H NMR and Fourier transform infrared spectroscopies and transmission electron microscopy ( TEM), respectively. TEM analysis indicated that the core-shell hybrid particles were uniform with narrow size distributions. The particle size and zeta potential decreased with an increase of alkylvinylsulfonate surfactant from 2.5 to 6.0 wt%. X-ray photoelectron spectroscopy revealed that fluorine concentrated preferentially at the film surface during a film-formation process. The film formed from the fluorine-silicon modified polyacrylate showed much higher thermal stability than a film formed from polyacrylate and fluorine-modified polyacrylate. Contact angle results showed that a finished fabric had remarkable water repellency. © 2015 Society of Chemical Industry
