Abstract

ZnO nanoparticle–based multilayer nanocomposite films were fabricated on cationized woven cotton fabrics via layer-by-layer molecular self-assembly technique. For cationic surface charge, cotton fabrics were pretreated with 2,3-epoxypropyltrimethylammonium chloride (EP3MAC) by pad-batch method. XPS and SEM were used to examine the deposited nano-ZnO multilayer films on the cotton fabrics. The nano-ZnO films deposited on cotton fabrics exhibited excellent antimicrobial activity against Staphylococcus aureus bacteria. The results also showed that the coated fabrics with nano-ZnO multilayer films enhanced the protection of cotton fabrics from UV radiation. Physical tests (tensile strength of weft and warp yarns, air permeability and whiteness values) were performed on the fabrics before and after the treatment with ZnO nanoparticles to evaluate the effect of layer-by-layer (LbL) process on cotton fabrics properties.

Highlights

The results showed that the coated fabrics with nano-ZnO multilayer films enhanced the protection of cotton fabrics from UV radiation
ZnO nanoparticles assembly for the multilayer film formation on the cotton fabrics were prepared by layer-bylayer deposition process
The Scanning electron microscopy (SEM) micrograph results indicated a significant difference in the morphology of the fibers before and after the LbL deposition process

Summary

Introduction

The LbL technique provides opportunity to improve the surface properties of textile fibers by depositing nanolayers of polyelectrolytes, charged nanoparticles and non-reactive dyes in a controlled manner. An attempt was made to improve functional cotton fabrics by the deposition of multilayer films containing ZnO nanoparticle. The positively charged cotton fabrics were immersed into the sequential solutions alternately for 5-min periods: (a) anionic ZnO colloid solution (b) deionized water, (c) cationic ZnO colloid solution, (d) deionized water. This deposition cycle was considered as one cycle depositing 2 layers and repeated until 10 and 16 multilayer ZnO films were deposited on cotton fibers. The multilayer film–deposited cotton fabrics according to Australian/New Zealand Standard AS/NZS 4399:1996
