A (meth)acrylate copolymer grafted with long fluorinated side chains (AGLF) was synthesized successfully through a two‐step procedure. First, a carboxyl terminated fluoropolymer, poly(2,2,3,4,4,4‐hexafluorobutyl methacrylate) was synthesized by conventional radical polymerization in the presence of 3‐mercaptopropionic acid as chain transfer agent. And then the fluoropolymer was grafted to the in‐house synthesized polyacrylate (MMA‐r‐BA‐r‐GMA). Fourier transform infrared spectroscopy and 1H‐nuclear magnetic resonance spectroscopy were employed to verify the synthesis of AGLF. Moreover, the surface properties were investigated by contact angle measurement and X‐ray photoelectron spectroscopy. The results proved that a small amount of poly(2,2,3,4,4,4‐hexafluorobutyl methacrylate) addition can create a hydrophobic surface effectively. Furthermore, the X‐ray photoelectron spectroscopy results showed that it is the AGLF grafted with longer fluorinated side chain that have more fluorine atoms enriched on the surface and thus performed better hydrophobicity and lipophobicity. Testified by thermogravimetric analysis and differential scanning calorimetry, it was found that AGLF films have excellent thermal properties. © 2017 Wiley Periodicals, Inc. J. Appl. Polym.

“…Thus, ink shrinking is a more challenging test than the liquid CA and SA tests. While liquid CA and SA values have often been reported in the past, − high CA values and clean liquid sliding do not automatically indicate that a coating possesses antismudge properties. This study suggests that a high degree of coating cross-linking is essential for achieving a robust and full-fledged antismudge coating.…”

“…We note that fluorinated compounds have been previously incorporated into UV-curable formulations to enhance the chemical resistance of the resultant coatings. − However, most prior studies failed to go beyond reporting the static CAs of several liquids in the characterization of the wetting properties of the final products. The contraction of ink and paint traces, which is more challenging to achieve than liquid sliding but deemed an essential qualification for an antismudge coating, were seldom reported.…”

Current antismudge coatings that bear nano-pools of a grafted liquid ingredient for dewetting enablement (NP-GLIDE) are cured at high temperatures, which are undesirable for application on heat-sensitive substrates. Reported herein is the development of a NP-GLIDE coating that can be photocured at room temperature. Of the various formulations that have been tested, robust coatings were obtained from one recipe consisting of a photoinitiator, a trifunctional monomer that bears three double bonds, and a graft copolymer. The last bears pendent double bonds and a poly(dimethylsiloxane) (PDMS) side chain as the antismudge agent. Coatings were prepared by casting films from a solution containing these three components and then photolyzing the resultant films. A systematic study revealed that the liquid sliding property developed on the coating at a lower cross-linking density than that required for ink to contract. Further, retaining the ability to contract ink traces after many writing and erasing cycles was the most demanding of the three antismudge tests. For our optimized formulation, only 5 min of irradiation was required to yield a transparent coating with superior antismudge properties. Moreover, irradiating selected regions and then removing, with a solvent, reagents in the nonirradiated regions can yield a surface with patterned wettability. These advantageous properties of the new photocurable coating facilitate its applications.

“…To overcome these disadvantages, the copolymerization of fluorinated acrylates with other monomers and blending fluorinecontaining acrylate polymers with fluorine-free acrylate polymers (Wang et al 2015) is an appropriate way. The fluorinated acrylate copolymers can be synthesized by block copolymerization (Zhao et al 2011), graft copolymerization (Tan, Liu, and Wang 2016), random copolymerization (Xu et al 2016) and core-shell copolymerization (Li, Zeng, et al 2014).…”

The incompatibility and phase separation of fluorinated acrylate polymer/natural rubber (NR) blend was obtained due to polarity mismatch of polymeric constituents in the blend. To decrease the phase separation in the composite, the graft copolymerization was a favorite method to enhance the compatibility of the blends. In this study, 2,2,2-trifluoroethyl methacrylate (TFEMA) was grafted onto NR backbone, which was assisted by methyl methacrylate (MMA) acting as a co-monomer for enhancing the grafting efficiency (GE). The graft copolymerization was carried out by emulsion-grafting process via free radical using potassium persulphate (KPS) as an initiator. The grafting properties were investigated as a functions of initiator concentration, MMA/TFEMA wt ratio, reaction temperature and reaction time. Under the optimum conditions (condition: 50/50 (w/w) of MMA/TFEMA, 0.75 phr of KPS at 60 °C for 4 h) the obtained gross graft NR (GNR) contained the maximum %GE and grafted TFEMA content as 23.6% and 7.3 mol%, respectively, with 3.8% gel content. The chemical structure of GNR after soxhlet extraction was analyzed by using attenuated total reflectance Fourier transform infrared spectroscopy (ATR-FTIR) and nuclear magnetic resonance spectroscopy (NMR). The morphology of GNR latex characterized by using transmission electron microscopy (TEM) was core-shell type. The graft product was then blended with PTFEMA to form modified PTFEMA films. The compatibility testing between polymeric constituents in the films was observed via Molau test and atomic force microscope (AFM). Water and hexadecane contact angles, surface energy and analysis of mechanical and thermal properties of the obtained films were also examined. It was observed that the addition of GNR provided the better surface and mechanical properties of the modified PTFEMA films than that of non-grafted NR.
