Clean Sono-synthesis of ZnO on Cotton/Nylon Fabric Using Dopamine: Photocatalytic, Hydrophilic, Antibacterial Features

In this paper, zinc oxide nanoparticles (NPs) were synthesized through sonication method as a green technique on 50/50 nylon/cotton (N/C) blend fabric to create multi-functional purposes. The N/C blend fabric was treated with zinc acetate as an initial material to synthesis ZnO NPs in presence of dopamine hydrochloride (DP). Herein, different concentrations of DP (0.01, 0.02, 0.05 and 0.50 g/l) were used to investigate its effect on characterizations of the treated fabrics with zinc acetate. Surface of the raw and treated fabrics was characterized via Field emission scanning electron microscopy (FESEM), X-ray diffractometer (XRD) and UV-Visible absorption spectroscopy. The weight percentage of the zinc on the fabric was roughly determined by EDX analysis. The DP perfectively affected on the morphology of ZnO NPs changed their shape to the nanosheets. The hydroxyl groups on the DP create appropriate conditions for adsorption of the more ZnO NPs on surface of the fabric, consequently increasing degradation rate of methylene blue. In addition, antibacterial activities of the ZnO NPs were significantly growing to 100% against Escherichia coli. Overall, this work indicates that DP can enhance some important functions of ZnO NPs on the N/C blend fabric including hydrophilic properties, photo and bio activities.

Automated summary

In this study, zinc oxide nanoparticles were synthesized using a sonication method on a nylon/cotton blend fabric for multifunctional purposes. The presence of dopamine hydrochloride affected the morphology of the ZnO NPs, increasing their adsorption on the fabric surface and enhancing degradation rate of methylene blue and antibacterial activities against Escherichia coli. This work demonstrates that dopamine hydrochloride can enhance the functionality of zinc oxide nanoparticles on the blend fabric, including hydrophilic properties, photo, and bio activities.
