    • Abstract


      Fabrication of icephobic and hydrophobic coating is a challenge of recent researches. In this article, we study the icephobicity and hydrophobicity of a nanocomposite from silica-titanium oxide nanoparticles in the polyvinylidenefluoride matrix. The surface energy of the prepared nanocomposites was tested by measuring the contact angle of different liquid droplets. Results show that the wettability is dependent on the concentration of nanoparticles, and the minimum surface energy of the prepared surface is 22.6 mJm$^{-2}$. In addition, icephobicity tests for cooled substrate show that the contact angle of the water droplet reduces to about 115° after freezing. Moreover, the icing test in the freezer shows a decrease in humidity freezing on the surface down to 25 g m$^{–2}$. Finally, stability tests in harsh environmental conditions such as UV radiation and heating indicate that the surface is substantially stable.
