Nanocoating on cotton fabric with nitrogen-doped graphene quantum dots/titanium dioxide/PVA: an erythemal UV protection and photoluminescent finishing

Prolonged exposure to ultraviolet (UV) radiation from the sun can result in several skin problems, such as accelerating aging, burns, blemishes, or even cancer. Even when wearing clothes, there is still a risk that user will be exposed UV and suffer damage. Therefore, it necessary apply anti-UV treatments clothes fabrics used, so users become safe. Nitrogen doped graphene quantum dots (N-GQD) titanium dioxide (TiO2) NPs are materials have broad spectrum of absorption promising candidates applied functional finishing use on textile materials, giving textiles property anti-UV. The aim this research evaluate synergy effect between N-GQD TiO2 getting nanocoating cotton fabric, add photoluminescent properties. nanocoatings obtained were via industrial discontinuous method, high-pressure high-temperature exhaustion process fabric using polyvinyl alcohol binding agent. According protection assessment, was observed both excellent absorbers their factor (UPF) highly dependent concentrations used nanocoated fabrics. Thus, with TiO2, TiO2/N-GQD revealed an UPF +50, which established effectiveness protecting against radiation. They also withstand up 20 wash cycles no change UPF.
