  3. Abstract:
  4. A superhydrophobic nanocomposite coating was fabricated using a simple procedure. The nanocomposite is composed of an acrylic copolymer and modified silica nanoparticles. The acrylic copolymer was prepared by free radical copolymerization of methyl methacrylate and dodeycl methacrylate monomers. Silica nanoparticles were synthesized and modified with an alkyl silane reagent, hexadecyltrimethoxysilane. A mixture of acrylic copolymer and modified silica nanoparticles, dispersed in dichloromethane, was then sprayed on glass and filter paper surface. Chemical composition and structure of the coatings were investigated by FTIR, FESEM, AFM, 1H-NMR and GPC. The wettability of the prepared coating was examined by water contact angle measurement. The results showed that superhydrophobic surfaces with contact angle above 150° and rough structures were obtained. The prepared coatings also exhibited superoleophilic and self-cleaning properties. © 2018, Springer-Verlag GmbH Germany, part of Springer Nature
