A side chain fluorinated UV curable waterborne polyurethane was synthesis
via radical polymerization of isophorone dissocyanate (IPDI), polycarbonate glycol (PCDL),dimethylolpropionic acid (DMPA), hydroxyethyl methylacrylate (HEMA), pentaerythritol triacrylate (PETA), triethylamine (TEA) and dodecafluoroheptyl methacrylate (DFHMA). The structure and properties of the cured film were characterized by Fourier-transform infrared(FT-IR)spectroscopy, 1H NMR, optical contact angle measuring instruments, particle size analyzer, thermal gravimetric analyzer and electronic tensile machine. The results indicated that with the addition of DFHMA increased, the emulsion particle size and its distribution,the contact angle, the thermal stability and tensile strength were obviously improved and the water absorption decreased. When the content of DFHMA was 6%, the cured film showed an optimal comprehensive performance.
