“…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.

“… with the help of microscopy images. Number of researchers have shown that PDMS polyol and fluoro polyol contributes to phase separation and can affect impact resistance of their films. It is interesting, however, that the cross‐cut adhesion was not affected by this possible phase morphology.…”

In recent years, there have been significant interests among scientists around the world to design smart coatings that combine the standard desirable mechanical and chemical resistance properties with additional functionalities such as oil and water repellency, hydrophobicity, self-cleaning and gas barrier properties. In the present research work, advanced aqueous polyurethane dispersion (PUD) systems have been designed and developed using three different types of polyols as soft-segments. These polyols differ in their chemical structure, functionality, polarity, and interfacial properties. The effects of soy-based polyol, hydroxy-terminated perfluoropolyether, and hydroxy-terminated polydimethylsiloxane-on various mechanical properties of their uncross-linked and cross-linked films, and more specifically on their hydrophobicity and oil-resistance (oleophobicity) have been studied. Hydrophobicity of these coatings has been characterized by their Dynamic Contact Angle measurements and their oleophobicity by n-octane absorption method. The investigations showed that presence of fluorine and siloxane structures significantly improve the hydrophobicity and oil resistance of these coatings and it is possible to optimize these properties using suitable composition of PUDs.

“…The photopolymerization process is of great interest in industrial applications because of its superior features over conventional heat curing systems, such as lower energy consumption, less environmental pollution, lower process costs, high chemical stability and very rapid curing even at ambient temperatures (15)(16)(17). Because of these advantages, the photopolymerization process has been used widely in the coating and paint sectors (18).…”

In this study, a polypropylene (PP) mesh was used to prepare proton-and Li + conducting composite membranes for fuel cells and lithium rechargeable batteries, respectively. For the preparation of Li + conducting membrane, polypropylene mesh was first immersed in an electrolyte solution, which was composed of LiBF 4 and ethylene carbonate. Then the swollen membrane was immersed in an acetone solution of polyethylene glycol diacrylate (PEGDA), polyvinylidenefluoride-cohexafluoro-propylene and photoinitiator. Finally, PP fabric was taken out from the solution and exposed to UV irradiation. Furthermore, proton conducting membranes were prepared by immersing the PP mesh into a mixture of vinyl phosphonic acid, PEGDA and photoinitiator. Afterwards, samples were cured under UV light. PP-reinforced membranes designed for fuel cell applications exhibited a room temperature conductivity of 3.3 × 10 -3 mS/cm, while UV-cured electrolyte for Li batteries showed ionic conductivities in the range of 1.61 × 10 -3 -5.4 × 10 -3 S/cm with respect to temperature. In addition, for lithium-doped composite polymer electrolyte (CPE), the electrochemical stability window was negligible below 4.75 V vs. Li/Li + . It is concluded that lithium-doped CPE has suitable electrochemical stability to allow the use of high-voltage electrode couples.
