Green synthesis of Ag-Poly (styrene sulfonate) nanoparticles and their application in cotton fabric

Abstract

This paper presents a method for the controlled reduction of silver chloride (AgCl) by D-(+)-Maltose in the presence of poly(sodium 4-styrenesulfonate) (PSS). PSS, acting as a polyelectrolyte, plays a crucial role in the process by accommodating silver ions (Ag+) through electrostatic interactions during synthesis and stabilizing the resulting silver nanoparticles (AgNPs). UV-Vis spectra revealed distinct absorption bands characteristic of AgNPs, with the Ag-PSS ratio affecting the size and distribution of nanoparticles. Dynamic light scattering (DLS) and zeta potential measurements confirmed the relationship between silver concentration and nanoparticle uniformity. Layer-by-Layer (LbL) deposition of Ag-PSS nanohybrids on cotton fabric surfaces, offering a unique approach for fabric modification. Energy-Dispersive X-ray Spectroscopy (EDS) analysis demonstrated a consistent increase in silver content with an increase in bilayers. Scanning Electron Microscopy (SEM) revealed enhanced fiber roughness, indicating effective nanohybrid deposition. Elemental mapping showcased uniform elemental distribution across the fiber surface, underscoring the precision of the LbL technique. In conclusion, this study presents an effective method for achieving uniform surface modification of cotton fibers through LbL deposition of Ag-PSS nanohybrids.
