A green approach for In-situ synthesis of silver nanoparticles on cotton fabric by low pressure cold plasma

In the present research, silver nanoparticles (Ag NPs) were in-situ synthesized on cellulosic cotton fabric using low pressure cold plasma (LP) as a novel, green and one step method. No chemical reducing agents were applied and water vapor was used to reduce silver ions (Ag+) into silver nanoparticles. Washed Cotton fabrics were activated by oxygen plasma and then immersed in different concentrations of silver nitrate aqueous solutions (500 and 1000 ppm) followed by padding and air-drying. Finally, water vapor plasma treatment using argon gas for 10 min was used for in-situ synthesis of silver nanoparticles on the cotton fabric. The surface morphology was investigated by Field emission scanning electron microscopy (FE-SEM) and also the structural analysis was characterized by Energy Dispersive X-Ray Analysis (EDX), elemental mapping, X-ray diffraction analysis (XRD), and Attenuated Total Reflection-Fourier Transform Infrared (ATR-FTIR) spectroscopy. The obtained results confirmed the synthesis and evenly distribution of silver nanoparticles on cotton fabric.

Automated summary

In this study, silver nanoparticles were synthesized on cotton fabric using low pressure cold plasma and water vapor as a reducing agent. The synthesis and distribution of silver nanoparticles on the fabric were confirmed through various characterization techniques.
