Ultrasound irradiation based in-situ synthesis of star-like Tragacanth gum/zinc oxide nanoparticles on cotton fabric

Abstract

Application of natural biopolymers for green and safe synthesis of zinc oxide nanoparticles on the textiles is a novel and interesting approach. The present study offers the use of natural biopolymer, Tragacanth gum, as the reducing, stabilizing and binding agent for in-situ synthesis of zinc oxide nanoparticles on the cotton fabric. Ultrasonic irradiation leads to clean and easy synthesis of zinc oxide nanoparticles in short-time at low-temperature. FESEM/EDX, XRD, FT-IR spectroscopy, DSC, photocatalytic activities and antimicrobial assay are used to characterize Tragacanth gum/zinc oxide nanoparticles coated cotton fabric. The analysis confirmed synthesis of star-like zinc oxide nanoparticles with hexagonal wurtzite structure on the cotton fabric with the average particle size of 62nm. The finished cotton fabric showed a good photocatalytic activity on degradation of methylene blue and 100% antimicrobial properties with inhibition zone of 3.3±0.1, 3.1±0.1 and 3.0±0.1mm against Staphylococcus aureus, Escherichia coli and Candida albicans.

A review of antimicrobial fabric containing nanostructures metal‐based compound

“…ZnO also can be utilized in ointments, lotions, and sunscreens to protect skin from UV illumination due to it serves as the broadest spectrum UVA (315–400 nm) and UVB (280–315 nm) reflector . Recently, there are numerous studies investigating the use of ZnO NPs as antibacterial agent on diverse fields such as food , textile , and biomedical applications . Devanand Venkatasubbu et al have applied ZnO on food pathogens namely, Salmonella typhi , Klebsiella pneumoniae , and Shigella flexneri for investigating its antibacterial performance .…”

“…ZnO is susceptible to agglomerate in water due to high polarity of water leading to deposition . Thus, ZnO has been incorporated with many capping agents on synthesis of ZnO nanocomposite coated on textile such as multiamide compound , sulfated β‐cyclodextrin , hexamethyltriethyylene tetramine , chitosan , acacia , PVP , silica , Tragacanth gum , cellulose , polymer diallyl dimethyl ammonium chloride‐allyl glycidyl ether‐methacrylic , polystyrene‐ block ‐poly(acrylic acid) , hydrogel , and sodium alginate .…”

“…There are several ZnO NPs coating techniques studied such as pad‐dry‐cure , spraying and dipping hydrothermal , sonochemical , plasma treatment , and pulse laser ablation . Table shows the summary of ZnO NPs‐coated textile and its antibacterial effects.…”

“…The Zn ions from zinc nitrate solution bond with hydroxyl groups and carboxyl groups from Tragacanth gum and cotton before sonicate to form ZnO NPs. The analysis showed that the star‐like ZnO NPs with average particle size of 62 nm with antibacterial properties against S. aureus , E. coli , and C. albicans were observed . Varaprasad et al has successfully fabricated sodium alginate‐ZnO NPs grafted cotton fabric by sonochemical mean.…”

Sol-Gel Applications in Textile Finishing Processes

“…Multifunctional finishing has drawn much attention in the last decades with many studies on this subject. Table 1 summarized some researches about various functionalities on textile materials treated with in situ sol-gel method and sols with nanoparticles [82][83][84][85][86][87][88][89][90][91][92][93][94][95][96][97][98][99][100][101].…”
