One Step In-Situ Synthesis of Zinc Oxide Nanoparticles for Multifunctional Cotton Fabrics

Abstract

Zinc oxide nanoparticles (ZnO NPs) have acquired great significance in the textile sector due to their impressive efficiency and multifold utilization, such as antimicrobials, UV protection, photo catalytic activity, and self-cleaning. The aim of this work is in-situ growth of ZnO NPs on 100% cotton fabrics with the one-step hydrothermal method for preparation of multifunctional textile with UV protecting, antibacterial, and photo catalytic properties. Sodium hydroxide (NaOH) and Zinc nitrate hexahydrate [Zn(NO3)2·6H2O] were used as reactants for the growth of zinc oxide on the 100% cotton fabrics. The loaded amount of Zn contents on the cotton fabric was determined by using induced coupled plasma atomic emission spectroscopy (ICP-AES). The surface morphological characterization of deposited ZnO NPs was examined, employing scanning electron microscopy (SEM), X-ray powder diffraction (XRD) and, Fourier- transform infrared spectroscopy (FTIR). The characterization results showed the presence of ZnO NPs on cotton fabrics having hexagonal wurtzite crystalline structure. The synthesized ZnO NPs on fabrics exhibited promising results for antibacterial, UV protection, and photo catalytic performance.

Use of single particle inductively coupled plasma mass spectrometry for the study of zinc oxide nanoparticles released from fabric face masks

“…The SEM images of the mask fibers show that an in situ route might be the method for deposition of ZnO on the face mask fibers as the ex situ route would result in a pile-up of nanoparticles. 49 With an in situ method for deposition of metal oxide nanoparticles, the fabric was pre-loaded with a solution containing metal ions to allow penetration of the metal salt throughout the structure of the fabric before in situ conversion of the metal ions to metal oxide nanoparticles. 49 With in situ preparation of ZnO particles on the fabric, the particles normally adhere more securely to the fabric.…”

As the particles are not loaded by the coating method, the leaching of nanoparticles may not be so significant during the washing process.…”

Nanotechnologies in Textiles

“…A growing interest in multifunctional textiles exhibiting antimicrobial properties [13,14], UV protection, photocatalytic and self-cleaning properties [15,16], fosters the development of hybrid nanomaterials, their synthesis, and deposition methods. Silver nanoparticles were known for years as antimicrobial material able to fight against severe infections related to antibiotic-resistant bacteria.…”

“…Metal oxide nanomaterials like zinc oxide nanoparticles (ZnO NPs) are attracting a lot of attention in textiles as traditional material yarns can be efficiently decorated with these nanomaterials, bringing the necessary functionalities related to the wide optical band gap of ZnO [15,16]. Simple and sustainable ZnO deposition methods onto the textile are the key limiting factors for upscaling and mass production of multifunctional nanotextiles.…”

“…Simple and sustainable ZnO deposition methods onto the textile are the key limiting factors for upscaling and mass production of multifunctional nanotextiles. Javed et al [15] proposed a one-step hydrothermal method for deposition of ZnO from sodium hydroxide (NaOH) and zinc nitrate hexahydrate [Zn(NO 3 ) 2 •6H 2 O] Optimized concentrations yielded 6.091 g/kg of Zn deposited on the cotton fabric. The amount of ZnO NPs on the surface of the fabric directly correlated with the antibacterial efficacy for E. coli and S. aureus bacteria and with catalytic activity confirmed using methyl orange.…”
