Synthesis of Silver Nanoparticles and Exhaustion on Cotton Fabric Simultaneously Using Laser Ablation Method

摘要

In this experimental research, the silver nanoparticles were synthesized on cotton fabric using laser ablation method in the same bath. Also the effects of the size of silver nanoparticles (NPs) on the structural and antibacterial properties of silver NP-coated cotton fabric have been investigated experimentally. A pulsed laser beam was used for synthesis of Ag NPs on cotton fabric. Pulses of a Q-switched Nd:YAG laser of 1064 nm wavelengths at 7 ns pulse width and different fluencies was employed to irradiate the Ag target in deionized water in the presence of cotton fabric. Four samples were prepared using different laser fluencies. The amount, size, morphology, and structure of produced NPs were studied using their spectrum in the range of UV to IR, and scanning electron microscopy methods. Fabrics were polluted by gram-positiveStaphylococcus aureusbacteria. The colony counting method was used to investigate the antibacterial activity of prepared cotton samples. Results show that laser ablation for synthesis of Ag nanoparticles on cotton fabric is an inexpensive fast method for producing antibacterial fabrics.
