چکیده مقاله:
Multifunctional wearable e-textiles are increasingly popular since such technology makes life safer, healthier, and more comfortable. This technology allows the production of highly innovative and intelligent e-textile garments that can perform as a sensor, actuator, power generator, and energy storage device all at the same time. Metallic conductive materials generally use to functionalize textiles, such as silver (Ag) and copper (Cu), are expensive, toxic, nonbiodegradable, and unstable. Graphene has opened up a wide range of flexible electronics applications due to its outstanding electrical, mechanical, and other performance properties. Graphene-based materials, such as GO and rGO, have already shown great promise by being fabricated into environmental friendly wearable e-textiles. The traditional method of coating textiles with rGO usually goes via coating textiles with GO first, followed by subsequent reduction by partial restoration of the sp2 structure [1]. Taking into account that the reduction process carried out in basic conditions and wool is unstable in basic condition and loses its strength, this method is not suitable for the functionalization of wool fabric. In this study, in order of functionalization of textiles, before coating on textile, rGO was reduced using hydrazine hydrate as reducing agent and then was sulfonated. Finally, the resulting dispersion was coated on textiles and the effect of various parameters such as pH, treatment time and temperature on the conductivity of the fabrics was studied [2-3]. This wool-sulfonated GO exhibits high electrical conductivity under various conditions. The FT-IR spectrum confirmed the structure of sulfonated GO.
