Abstract
Cross-linked acrylate emulsion modified with fluorine-silicon modified was prepared to create a strongly hydrophobic polymer surface. Mixed green surfactants of sodium lauroylglutamate (SLG) alkyl poly-glycosides (APG) was used as the emulsifiers. Vinyltriethoxysilane (VTES), hexafluorobutylmethacrylate (HFMA) and hydroxypropyl methacrylate (HPMA) were used as the functional monomers in the polymerization. The structure and properties of the resultant emulsions and their films were characterized by Fourier transform infrared spectrometer (FT[1]IR), Zetatrac dynamic light scattering detector, differential scanning calorimetry (DSC), DataPhysics contact angle meter and thermogravimetry (TGA). In comparison with the conventional polyacrylate emulsion, the thermal stability and water resistance of the film of the resultant emulsion are improved.
