چکیده مقاله

This study introduces an innovative approach to enhance cotton fibers with integrated self-cleaning and antibacterial properties. By combining the potential of carbon quantum dots (CQDs) and silver nanoparticles (AgNPs), a distinct fabric modification strategy is developed. The synthesis mechanism of CQDs is outlined, alongside fabric activation using benzenesulfonyl chloride and triethylamine. The process of depositing CQDs and AgNPs onto the fabric surface is explained, emphasizing the importance of surface interactions and chemical affinity. Comprehensive characterization techniques, including scanning electron microscopy (SEM), energy-dispersive X-ray spectroscopy (EDS), Fourier-transform infrared spectroscopy (FTIR), and X-ray diffraction (XRD) were done to confirm the successful coating and nanoparticle integration. The confirmation of nanoparticles on the cotton fabric surface and subsequent results indicate an exceptional 128% increase in degradation activity compared to untreated fabric, coupled with significant enhancement in antibacterial efficacy against both Gram-positive and Gram-negative bacteria. In this report, the development of advanced multifunctional cotton fibers with improved stain resistance, self-cleaning capability, and enhanced antibacterial efficacy has been investigated.
