| Abstract: | The copolymer dodecafluorohaptyl-methyl methacrylate-octadecyl acrylate(DMFA-SA-MMA) was synthesized by emulsion polymerization and then applied to epoxy coating to reduce its surface energy.The copolymer and coating were characterized by Fourier transform infrared spectrum(FT-IR),1H nuclear magnetic resonance spectrum(1H-NMR) and scanning electron microscope(SEM),respectively.The influence of copolymer on surface energy and contact angle was investigated.The result indicates that the surface energy of the coating is reduced greatly,due to the addition of the Fluorine-containing acrylate copolymer and the formation of microstructure.When the ammount is 10%,The surface energy is merely 4.56 mN/m,and contact angle is 136°. |
