Description
Summary:— In this work, a novel, fast and one step sonochemical synthesis and deposition technique to prepare silver nanoparticles (AgNPs) coated cotton fabrics is developed. The reaction medium consisted of silver nitratre, hexamethylenetetramine as reducing agent and polyvinylpyrrolidone as the polymeric stabilizer. The AgNPs-deposited cotton fabrics were characterized by UV-visible spectroscopy, X-ray diffraction, attenuated total reflectance Fourier transform infrared spectroscopy, dynamic light scattering and scanning electron microscopy techniques. The hydrodynamic diameters of the particles were found to increase from 32 to 144 nm with increase in the irradiation time from 30 to 90 min. Electron micrographs of the AgNPs deposited cotton fabrics showed uniform deposition of the particles on cotton. The AgNPs-deposited cotton fabrics showed excellent antibacterial activities against Gram-negative bacteria ( Escherichia coli and Pseudomonas aeruginosa ) and moderate antimicrobial activities against Gram-positive bacteria ( Staphylococcus aureus and Bacillus subtilis ).
