A series of UV-curable waterborne fluorinated polyurethane (UV-WFPU) were prepared successfully based on novel fluorinated side chain extender (F-TMP). The structure of F-TMP and particle size of UV-WFPU dispersions, contact angle (CA) and surface free energy, morphol., and damping property of UV-WFPU films were characterized through Fourier transform IR spectroscopy, nanoparticle size anal., contact angle test, scanning electron microscope and dynamic mech. anal. (DMA), resp. The results indicated that UV-WFPU dispersions had a particle size between 49.01 and 61.52 nm. The latex particle size and tan æ?value of UV-WFPU films increased with the increase in F-TMP contents. The studies of surface properties confirmed that UV-WFPU films based on F-TMP had outstanding hydrophobicity properties. The highest CA of water and lowest surface free energy of UV-WFPU films reached 96.2æ?and 21.17 mJ/m2, resp. Meanwhile, the DMA results showed UV-WFPU films possessed great damping property which had the broad temperature range enhanced by F-TMP, with a maximum value at 190.4æ³C. The results of mech. properties showed that the addition of fluorine increased in the tensile strength of the film. And these films have potential application values in the tech. fields of damping, anti-corrosion and dust prevention.
