Green Synthesis of ZnO and SiO2 Nanoparticles and its potential application on Pineapple Fabric to impart multifunctional properties

Abstract

Abstract The present study aims to synthesize ZnO and SiO2 nanoparticles by using the green technique and applied to pineapple fabric to impart multifunctional properties. ZnO nanoparticles were synthesized by using Zinc Acetate where the mixture of Acalypha Indica and Citrus aurantifolia peel powder was used as the catalyst. Also, SiO2 nanoparticles were synthesized from sugarcane bagasse which was the primary source of silica. Final SiO2 nanoparticles were obtained by the addition of NaOH and HNO3. Afterward, the synthesized particles were coated on the pineapple fabric by using the dip-pad-dry-cure method along with the addition of 2 wt% acrylic binder. The structural properties as well as the microstructure and chemistry of these coated samples were characterized by Fourier Transform Infrared Spectroscopy (FT-IR) and Scanning Electron Microscopy (SEM) analysis. Also, the UV resistance, resistance against microorganisms, and super-hydrophobicity properties were evaluated by UV/VIS Spectrophotometer analysis, antimicrobial test, and spray rating test accordingly where the nanoparticle coated sample showed a very good absorbency in UV rays, superhydrophobic properties, and a very good resistance against microorganism maintaining optimum tensile.
