“…The unique characteristics of fluoropolymers such as oleo‐ and hydrophobicity, excellent thermal and chemical properties, photochemical stability, and low surface energy have attracted great attention in coating technology . The incorporation of fluorine atoms can lower the surface energy and enhance the hydrophobicity of waterborne UV‐curable polyurethane.…”

Novel waterborne UV-curable polyurethane containing long fluorinated side chains (WUVFPU) was prepared and the fluorinated component was incorporated by two novel fluorinated macromolecular diols (FDO) with different chain length as chain extender. FDO was synthesized via free radical polymerization of hexafluorobutyl methacrylate (HFBMA) using 1-thioglycerol (TG) as chain transfer agent. Extremely low dosage of FDO incorporated could change the surface property significantly. The influence of both the content and chain length of FDO on the surface energy, surface composition and morphology were investigated by contact angle measurement, XPS and AFM. Surface energy significantly decreased at extremely low concentration of FDO. The hydrophobicity was enhanced with increasing both the content and the chain length of FDO. XPS and AFM results revealed the enhancing hydrophobicity was attributed to the enrichment of F atoms and rougher surface morphology. Gel content, pencil hardness, adhesion, and optical transmittance tests were employed to investigate the coating properties of the UV-cured films. The preparation and investigation of WUVFPU might provide better understanding of the influence of fluorinated chain length on the properties of polyurethane for theory. Moreover, it might provide a facile and effective route to prepare polyurethane materials with low surface energy for engineering and industry.

“…These results were well consistent with the contact angle measurement. Data from XPS analysis was a strong evidence confirming the fact that long fluorinated side chains, which have greater thermodynamic driving force to migrate to the surface due to the incompatibility with the matrix, are more efficient and effective to migrate and concentrate on the surface than short pendent fluorinated group …”

A novel macromonomer containing fluorinated units (PHFBMA-GMA) was synthesized through a two-step procedure: firstly, hexafluoro-butyl methacrylate (HFBMA) was polymerized in the presence of functional chain transfer agent 3mercaptopropionic acid (MPA) and then the carboxyl acid group terminated polymer was end-capped with glycidyl methacrylate (GMA). Chemical structures of PHFBMA-GMA were characterized by gel permeation chromatography, fourier transform infrared spectroscopy (FTIR), and 1 H nuclear magnetic resonance (NMR). Subsequently, PHFBMA-GMA was employed as reactive surface additives added into UV-cured polyacrylate to modify UV-curable coatings. It is convenient to control the tail length of the fluorinated segments in this study by adjusting the ratio of initiator and chain transfer agent. The influence of both the concentration and the molecular weight of PHFBMA-GMA on the surface properties of UV-cured films was investigated. With increasing both the concentration and the molecular weight of PHFBMA-GMA, the surface energy of the UV-cured films decreased. X-ray photoelectron spectroscopy was employed to characterize and quantify the surface composition and the results confirm the enrichment of fluorinate atoms on the surface. Moreover, the physical properties of UV-cured films, such as gel content, water absorption, pencil hardness, adhesion, chemical resistance, mechanical properties, optical transmittance, and thermal properties, were also investigated in detail. The novel macromonomer was economical but effective to modify the properties of the UV-curable coatings. V C 2015 Wiley Periodicals, Inc. J. Appl. Polym. Sci. 2016, 133, 43116.
