| Abstract Scope |
Polymer based hydrophobic titania nano fibers were fabricated using a simple Low Volume Medium Pressure(LVMP) spray gun. The FE-SEM studies showed that it resembled the nanofibers produced by electro spinning method. Spraying parallel to the length of the glass slide gave better contact angle values and the fibers were more entangled. The hydrophobicity was developed in the coating immediately after spraying. The contact angle measurements were done using Goniometer. Curing the fibers in hot air oven at 80°C reduced the contact angles. Three different sources of titania were experimented. Powder characterization was done by XRD, Raman spectroscope. A set of nine experiments based on Taguchi’s Method were also conducted for contact angle optimization. Even a small amount (0.03g) of hydrothermal titania with 0.7g of polystyrene gave a contact angle as high as 149.77°, which is close to super hydrophobic range. |
