ZnO nanoparticles for enhanced characteristics of cotton fabrics

Scientists have prepared a coating of modified zinc oxide nanoparticles on cotton fabrics for enhanced functional characteristics.

The incorporation of nanoparticles (NPs) into textile fabrics can transform ordinary products to endow the new functional characteristics owing to their interesting surface characteristics. The surface functionalisation of NPs can play a key role in controlling the colloidal stability followed by interactions between substrate and NPs leading to enhanced functional characteristics.

Significant improvements

Now, the synthesis of zinc oxide NPs was carried out through hydrothermal method. The surface of NPs was modified using silanol and tertiary amine-based coupling agents. The functionalised NPs exhibited stable dispersion with higher zeta potential and have a smaller size. A significant improvement in the ultraviolet protection factor value and antibacterial activity of treated cotton fabrics was observed.

The study has been published in Journal of Coatings Technology and Research Volume 19, 2022.
