Characterization of a low-wettable surface based on perfluoroalkyl acrylate copolymers

Laundering Durability of Superhydrophobic Cotton Fabric

“…FT-IR spectroscopy (attenuated total refl ectance (ATR) mode) confi rmed the existence of poly( 1H,1H,2H,2H -nonafl uorohexyl-1-acrylate) graft chains in the cotton-F4 samples, where the new absorption bands at 1236 cm − 1 and 1737 cm − 1 can be attributed to CF 3 and ester groups in the graft chains (Figure 1 b). [ 10 ] A decrease in the hydroxyl signal along with an increase in ether linkages would suggest chemical bonding between the graft chains and the cotton fabric. Figure 1 c shows that the hydrophobicity of the cotton-F4 is dependent on the DG, where the CA with water is stable and greater than 150 ° when the DG is higher than 10%.…”

Preparation and characterization of fluorinated acrylate copolymer latexes by miniemulsion polymerization under microwave irradiation

“…Therefore, fluorinated polyacrylate latexes have been used progressively in a wide range of applications such as biomaterials, microelectronics, antifogging, and antifouling applications [5][6][7], especially as surface coatings for textile, paper and leather, because their presence can introduce a number of unique physical and chemical surface properties [1,8]. Many fluorinated or perfluorinated (meth)acrylate monomers have been studied with regard to the synthesis of copolymers with conventional acrylate in aqueous emulsions by radical polymerization methods [1,[5][6][7][8][9][10]. Most of them are the copolymers of fluorinated acrylate with long perfluoroalkyl groups (>7 fluorocarbons).…”

The Synthesis and Morphology of a Perfluoroalkyl Oligosiloxane@SiO2 Resin and Its Performance in Anti-Fingerprint Coating

“…Moreover, micro-/nano-rough structure is an essential and primary factor in preparation of super-hydrophobic surfaces [25]. Therefore, exploring the macro-and micro-morphology of the FSi@SiO2 resin [26] will help us to better understand why the coating exhibits strong hydro-and oleo-phobicity and reveals the anti-fingerprint mechanism of FSi@SiO2.…”
