“…As can be seen in Figure 3, the total surface energy for the MMA–FHMA copolymers decreases sharply with increasing FHMA content, resulting in a reduction of the surface energy by a factor of about 2 at an incorporation of 15 mol % of FHMA. Similar trends were observed for copolymers using styrene and fluoroalkyl‐modified styrene 23, 24. This indicates a preferential orientation of the fluoroalkyl side chain to the air–polymer surface.…”

This study aimed at reducing the surface energy of coatings by copolymerization of commonly used monomers with fluorine‐containing monomers. Copolymers of 1,1‐dihydroperfluoroheptyl methacrylate (FHMA) and methyl methacrylate (MMA) or butyl acrylate (BA) are prepared by low‐conversion polymerization in solution. Using 1H‐NMR data and nonlinear least‐squares data fitting, reactivity ratios of these systems at 80°C are determined to be rFHMA = 1.31, rMMA = 0.76, and rFHMA = 3.15, rBA = 0.38, respectively. We assume that the penultimate unit effect plays an important role in these systems. Introduction of the perfluoroalkyl side chain lowers the polymer surface energy significantly; copolymers of MMA and FHMA show a reduction in total surface energy of about 50 % at a content of 15 mol % FHMA as compared with pure PMMA. The attainable reduction in surface energy is much larger than with, for example, Teflon. This is due to the preferential adsorption of the —CF3 groups of the fluoroalkyl side chain, if compared to that of the —CF2— groups of Teflon. © 2000 John Wiley & Sons, Inc.

“…Therefore a low $\gamma_{\rm s}^{\rm d}$ value is strongly related to an optimal number of NFD units or to an optimal number of C 4 F 9 side chains. These results are consistent with a well‐defined concentration of CF 3 and CF 2 groups at the surface of the films and also with the more efficient association of the C 4 F 9 side chain leading to a minimal interfacial energy 10–12. The behaviour of these film surfaces seems to be very different for copolymers and blends.…”

The well‐known polyetherimide (ULTEM 1000) is obtained by step‐reaction of bisphenol. A diphthalic anhydride (BAPA) with m‐phenylene diamine and newly related fluorinated poly etherimides synthesized from BAPA and 2,3‐bis(2,2,3,3,4,4,5,5,5‐nonafluoropentyl)butan‐1,4 diamine (NFD) led to compatible blends over the entire range of composition. Miscible one‐phase blends have been suggested by a good correlation of Tg versus NFD monomer unit weight fraction (w) (Fox and Couchman equations) and a regular morphology by scanning electron microscopy. Surface energy of blend films fell from 45.3 to 27.4 mJ m−2 for w ≥ 0.1 corresponding to a NFD molar fraction y ≥ 0.06. Cast‐evaporated films from fluorinated copolyetherimides and blends with y < 0.15 were ductile and gave conveniently hydrophobic non‐porous membranes that withstood the experimental conditions of pervaporation tests.

“…Acrylic copolymers containing perfluoroalkyl side chains have been the focus of many studies, because of the good reactivity of perfluorinated acrylate with fluorine-free acrylate and good adhesion to the matrices [13][14][15]. The fluorinated side groups in fluorinated acrylic copolymers have emerged preferentially at the coating-air surface [16][17][18][19][20]. Fluorinated acrylic copolymer films not only retain the original properties of polyacrylate films, such as good adhesion to the matrix, but also have better durability as well as good antifouling property.…”

A series of UV-curable polyurethane acrylates containing fluorinated acrylic monomer (heptadecafluorodecyl methacrylate, PFA, 6 wt%)/ vinyltrimethoxysilane (VTMS, 0-9 wt%) [FPUA6/0, FPUA6/3, FPUA6/6 and FPUA6/9, where the numbers indicate the wt% of PFA/VTMS] were synthesized from a reactive urethane oligomer (40 wt%) and diluents (60 wt%). This study examined the effect of bulky VTMS (0-9 wt%)/bulky IBOA (34-25 wt%) weight ratio on the properties of the UV-curable polyurethane acrylates for transparent anti-fouling coating materials. In the wavelength range of 400-800 nm, the transmittance % of the FPUA film samples increased markedly up to nearly 100 % with increase in the VTMS content up to 9 wt%. As the VTMS content increased, the storage modulus/ tensile modulus/hardness of the UV-cured film samples increased significantly and the tensile strength/glass transition temperature increased a little; however, the elongation at break decreased significantly. XPS showed that the film-air surface of the UV-cured polyurethane acrylate film had a higher fluorine content than the filmdish interface indicating the gradient concentration of fluorine in the structure of the film from the film-air surface to the film-glass interface. As the VTMS content increased from 0 to 9 wt%, the surface tension of the UV-cured urethane acrylate films decreased from 17.2 to 15.9 mN/m, whereas the water/methylene iodide contact angles of the film-air surface increased significantly from 107.9/80.9°to 114.2.9/ 84.2°. These results suggest that the UV-curable polyurethane acrylate containing 9 & Han Do Kim
