lHighly conductive nano-silver textile for sensing hydrogen peroxide

A promising field of research is developing on flexible conducting textiles. There are many multifunctional applications, such as in wearable electronics, health monitoring, military, or as electrode surfaces in energy conversion and storage systems (supercapacitors, battery and fuel cells). Silver nanoparticle embedded-viscose fabrics produced by an electroless coating method have been demonstrated to give a resistance of 0.26 Omega cm(-1). A glassy carbon electrode with nano-Ag textile disc attached (Ag-VF/GC) exhibits a selective electro catalytic response towards H2O2 even in the presence of interferences like fructose, sucrose, glutamic acid, tartaric acid, ascorbic acid, uric acid, nitrate, dopamine, and glucose. The modified electrode has shown a sensitivity of 35.97 mu A mM(-1) for hydrogen peroxide, with a detection limit of 13 mu M across a wide linear range of 20 mu M to 33 mM H2O2. The effects of the fabric morphological changes after sensing of peroxide was further investigated using scanning electron microscopy (SEM), X-ray diffraction (XRD) and water contact angle studies.
