A fluorinated polyacrylate (DLHK) emulsion was prepared by copolymerization of dodecafluoroheptyl methacrylate (DFMA), lauryl acrylate (LA), 2-hydroxypropyl methacrylate(HPMA) and 3-(methylacryloxyl)propyltri- methoxy silane (MPMS) in the presence of anionic/nonionic surfactants. The structure and physicochemical properties of DLHK were characterized by Infrared spectrum (IR), 1H-nuclear magnetic resonance (1H-NMR) and Transition electron microscopy (TEM). Then the DLHK emulsion was utilized to prepare the fluorocarbon coating and effects of temperature and dosage of emulsion on surface properties of coating were discussed. Results show that the DLHK latexes possess core-shell structures with an average particle size of 131nm and zeta potential of -24.09 mV. The coating displays favorable water repellency and water contact angle on its surface is 128°when dosage of emulsion and curing temperature are 25g and 150℃, respectively.
