Synthesis of sulfated β‐cyclodextrin/cotton/ZnO nano composite for improve the antibacterial activity and dyeability with Azadirachta indica

Abstract

The sulfated b-cyclodextrin (sb-cd) was prepared from b-cyclodextrin and the sb-cd was crosslinked with cotton fabric using ethylenediaminetetraacetic acid (EDTA) as crosslinker. After crosslinking, the synthesized ZnO nanoparticles were padded on this fabric surface. Then, the treated fabrics were dyed with neem extract. The synthesized polymer, crosslinked and nanoparticle-treated cotton fabrics were characterized using fourier transform infrared spectroscopy (FTIR), X-ray diffraction (XRD), particle sized analyzer, and transmission electron microscopy (TEM) studies. The antibacterial test was done against Staphylococcus aureus and Escherichia coli bacterium. The composite coated with neem dyed cotton fabric has exhibited 71% of dye uptake with 2-3 fastness grade and it has 99% of antibacterial efficiency for S. aureus and 97% for E. coli bacterium.

Cellulose Nanocomposites

“…The antibacterial test was done against Staphylococous aureus and Escherichia coli bacterium. This type of cotton fabric is recommended for surgical cloths, wound cloths, all inner wears and sport wears (81). In another research, multifunctional cotton fabric assembled with Ag and ZnO nanoparticles was produced by one step, in situ synthesis via microwave irradiation.…”

Smart medical textiles based on cyclodextrins for curative or preventive patient care

“…In 2013, the synthesis of sulfated--CD/cotton/ZnO nano composite has been reported (Sundrarajan et al 2013). The sulfo--cyclodextrin (S--CD) was cross-linked with cotton fabric using ethylenediaminetetraacetic acid (EDTA).…”

Bioactive Hybrid Composite Membrane with Enhanced Antimicrobial Properties for Biomedical Applications

“…3(b) shows the FT-Ir spectrum of the A. indica depicted as a series of characteristics absorption bands at 1642 cm -1 , 1449 cm -1 , 1084 cm -1 representing the stretching of the -(C=O) group, deformation of the asymmetric -(CH 2 ) and vibrational stretching of the -(C-C) groups, respectively. The other notable peaks were at 3326cm -1 reflecting the stretching of the -(OH) group and at 2978cm -1 illustrating -(CH 2 ) stretching [26][27] . FT-Ir spectrum of hybrid chitosan system indicates that characteristic peak for chitosan/A.…”
