Fabrication and Simulation Properties of [SiO2 - TiO2] / Silan-Cellulose Acetate Nanocomposite for Self-Clean Surfaces Applications

In this work, nanocomposite films (SiO2-TiO2 / silan-cellulose acetate) fabricated by thermal spray coating method on heated glass substrates at 70 Celsius Degree. The adding (0, 10:1, 10:2, 10:3, 10:4) of (SiO2:TiO2) weight ratio was increased the water contact angle. The films have a good adhesion with glass substrates. All specimens have hydrophobic property. The process of preparing the hydrophobic composites was simulated, in addition to the simulation of the structural properties. The simulation was carried out using Gaussian program by employing Gauss view studio using density functional theory. The experimental results were compared with the simulation results, and they were of excellent agreement. The simulation results helped in analyzing and interpreting the practical results in a comprehensive manner. It can be concluded that the contact angles that content TiO2 nanoparticles of the films were greater than that of the pure film. The optimal value of weight ratio was at the ratio 10: 3 with a contact angle equal to 156.2, so the films acquired the super hydrophobic surfaces. Moreover, it can be concluded that the simulation was able to analyze the surface property of the composite and the reason for it having a hydrophobic property.
