Abstract
Several important practical applications, such as covid-19 front line worker garments and on-demand military apparel, require anti-water (hydrophobic) absorption and highly luminous clothing. Industrial and rapid production of these fabrics is highly expensive and under extensive research. In this work, we report an economical titania based superhydrophobic cotton and silk fabrics by wet chemical sol–gel dip coating technique. The structural characteristics of the textiles were studied using XRD, which revealed an anatase phase of titania. Wetting study on titania coated cotton and silk materials demonstrated contact angles of 146O and 136O, respectively. Additionally, in the ultraviolet and infrared wavelengths, diffused reflectance spectroscopy supported 84% and 92% reflectivity, respectively. As a result, the coated fabric proved to be an outstanding hydrophobic and reflective material that may be recommended for numerous maintenance-free apparel applications.
