2.5. Characterization
The absorption spectrum of AgNWs colloidal solution was recorded by ultraviolet–visible (UV–vis) spectroscopy with a Cary 100 spectrophotometer, using 10 mm path length quartz cuvettes. Microscopic investigations of the synthesized AgNWs and fabric samples were carried using KYKY-EM3200 scanning electron microscope (SEM). SEM images of AgNWs were taken without conductive coating. However, the fabric samples were mounted on conductive carbon adhesive tabs and images were taken after the samples had been sputter-coated (SC 7620 EMITECH) with a very thin layer of gold.
