    Development of a plasma activated multifunctional polyester fabric using zinc oxide nanoparticles and citronella oil microcapsules
    (Wydawnictwo Politechniki Łódzkiej, 2022) Mehravani, Behnaz; Nicolau, Talita; Ribeiro, Ana Isabel; Parente, Joana F.; Sousa, Vânia I.; Tavares, Carlos J.; Padrão, Jorge; Zille, Andrea
    There is a high demand for the development of textiles possessing multifunctional properties for outdoor, protective and health care applications. The coating of polyester (PES) textiles with metal nanoparticles and essential oils may act in a synergistic mode to obtain materials with improved antimicrobial and UV-protection properties. However, the lack of functional groups onto PES structure makes the adhesion of particles a difficult task. In this work, PES fabric was activated by dielectric barrier discharge (DBD) plasma treatment, and functionalized with zinc oxide nanoparticles (ZnO NPs) and poly (methyl methacrylate) (PMMA)-citronella microcapsules by dip-coating.

    In-situ green synthesis of zinc oxide nanoparticles (ZnO NPs) onto the cotton fabrics by neem (azardirachta indica) leaf extract
    (Wydawnictwo Politechniki Łódzkiej, 2022) Javed, Asif; Wiener, Jakub; Saskova, Jana; Militky, Jiri
    This research work was carried out for the green in-situ synthesis of ZnO nanoparticles onto the 100% cotton fabric. Zinc nitrate hexahydrate [Zn(NO3)2.6H2O] was used as precursor and the Neem (Azardirachta Indica) leaf extract was used as reducing agent. Scanning electron microscopy (SEM) and X ray diffraction (XRD) were done to investigate the surface morphology and characteristics of developed samples. Moreover the ultraviolet protection factor (UPF), UVA blocking %age, UVB blocking %age, and antibacterial properties were examined. The SEM and XRD confirmed the deposition of ZnO NPs onto the fabric having crystalline structure. The evaluated samples showed very excellent results for, UPF rating, UVA blocking %age, UVB blocking %age, and antibacterial properties.
