Abstract
A sustainable, fast, feasible, and controlled approach is reported for the synthesis of silver nanoparticle (AgNP). The extract from natural ash plant (Fraxinus excelsior) flower was used as bio-based reducing and stabilizing agent to synthesize AgNPs from AgNO3 precursor. The quantitative analysis of AgNP was performed by X-ray fluorescence (XRF) and inductively coupled plasma optical emission spectroscopy (iCP-OES) for solid and liquid samples, respectively. The XRF analysis of untreated and treated glass fabrics were 0, 379 ± 16, and 630 ± 19 PPM, respectively; whereas iCP OES provided the results by 0, 240, and 830 mg/L AgNPs presence on liquid solutions. The Scanning electron microscopy analysis (SEM) exhibited uniform and clear distributions of AgNP on glass surface. The SEM-deployed energy-disruptive X-ray (EDX) and elemental mapping analysis also reflects the clear presence of AgNPs on the surface of glass. Both the treated and untreated glass fabrics were subjected to Fourier transform infrared spectroscopy (FTIR) analysis. The luminescent features of the AgNP treated glass fabrics were also further investigated to assess the color properties. The treated glass substrates also provided bright and brilliant color appearances after treating with AgNPs. Overall, this method of AgNP synthesis would be a benchmark to create new routes of ecofriendly materials for the coloration of woven glass fabrics.
