oly¬(vinylchloride)-coated polyester fabrics are the most commonly used material in construction of structural fabric. Among different properties of these fabrics which are used as awning and canopies, resistance against dirt pick up and surface degradations, weathering, are the most important characteristics to ensure long-life aesthetic properties. Preparation of self-cleaning effect on surface of Poly¬(vinylchloride) is an effective technique to improve performance. Therefore, combination of a low surface energy material and nano particles was used to create effective roughness on the top of Poly¬(vinylchloride) surface. Adhesion decrease of dirt particles and water droplets to surface is obtained by decreasing the contact area. First, Poly¬(vinylchloride) plastisols with different amount of additives were prepared and coated on Polyster fabrics. The sample which had optimum properties was selected as base fabric for the next experiments. Second, different percentages of nano Titanium Dioxide and nano Zinc Oxide were dispersed in mixture of Perfluoroalkylacrylates and 2-isopropanol. These topcoating solutions were sprayed on the selected Poly¬(vinylchloride)-coated fabric. After dry-cure process, the effects of finishing on the topcoated sample properties were evaluated by measuring contact angle, sliding angle and 3M water repellency test. quantitative self-cleaning property of the samples was studied. Because of low abrasion fastness of topcoating, Improvement in topcoating, adhesion to the substrate was improved using surface functionalization by UV-Ozone treatment. The effect of different conditions of surface modification on the samples performance was studied by ATR-FTIR spectroscopy and Martindale wear-abrasion tester. Results obtained indicate that optimum percentage of Perfluoro¬alkylacrylates topcoating can increase water-repellent properties of Poly¬(vinylchloride). Furthermore, existence of 3% nano Titanium Dioxide created a superhydrophobic surface on Poly¬(vinylchloride) with high contact angle (150°) and very low sliding angle (2°). Super¬hydrophobicity which causes self-cleaning effect occurred due to low surface energy of Perfluoroalkylacrylates and multi-scale structured roughness on the surface. So, surface cleanability by water droplet was increased three times. Abrasion fastness of top coating was improved by surface oxidation via UV-Ozone surface treatments. ATR-FTIR analysis demonstrated that formation of oxygenated functional groups (such as C-O, C=O and O=C-O), improves Poly¬(vinylchloride) wettability and adhesion of topcoating to it. The longer time of exposure, the more oxygenated functional groups were created. At last, a superhydrophobic surface with self-cleaning property was produced which had not only good resistance to weathering like ultraviolet beam and rain, but also a good washing and abrasion fastness.
