Abstract
In this paper, we report on the surface functionalization of textile (cotton-polyester) fabrics with ZnO nanoplatelets by a simple two-step process, which can be easily translated into a highly convenient and cost-effective commercial process. In the first step, morphology-controlled ZnO nanoparticles in the form of flat platelets with high surface area were synthesized by a simple chemical reaction of aqueous solutions of Zn2+ salt, poly-vinyl alcohol (PVA), and sucrose. In the subsequent step, the textile fabrics were coated with a PVA-based nanocomposite of the derived ZnO nanoplatelets by solution immersion technique followed by thermal curing. The covalent interactions in the ZnO-PVA nanocomposite system supported the strong bonding of the ZnO nanoplatelets with the textile fabrics. The ZnO-functionalized textile fabrics showed significantly improved UV protection and self-cleaning features compared to the pristine fabrics.
