Abstract
A novel fluorinated methacrylate monomer (FMA) containing perfluorinated branched-short chain groups was successfully synthesized, and core-shell emulsions with different fluorine contents were prepared by two-step seed emulsion polymerization. The fluorinated polyacrylate (PFA) emulsion was characterized by fourier transform infrared spectroscopy (FTIR), dynamic light scattering (DLS) and transmission electron microscopy (TEM). By using of the prepared fluorinated polyacrylate (PFA) emulsion and silica sol, a convenient one-step spray method that led to substrates with efficient water repellency was developed. The water contact angle (WCA) of these coatings was up to 152°, and the water droplets can fall off freely. In addition, several varies substrates were coated and all of them exhibited superhydrophobicity in order to verify the universality of the coating, and the coatings had good adhesion on these substrates. The coated cotton fabric also had certain anti-fouling properties and acid-base resistance. These substrate independent coatings have the potential to be used in many fields.
