Abstract [en]

Recently, graphene has been used to obtain (E)-textiles. From an industry-relevant perspective, it is essential to introduce a process that could be scaled-up. We applied a cost-effective dip-coating method using bio-sourced agents for chemical adsorption of graphene oxide (GO). Polyester and viscose woven fabrics were treated with an aqueous solution of glycerol (4 g.L-1) to overcome the electrostatic repulsion among fibers and GO and then dip-coated with a dispersion of GO. The results are homogeneous GO coating with one to a few layers of GO nano-sheets. Further, The GO was chemically reduced to rGO, by using tannic acid (10 g.L-1) as a bio-sourced reducing agent. This brings electrical conductivity to rGO nano-sheets having an electrical resistance of 2±1 and 10±4 kΩ/sq for polyester and viscose fibers respectively. Afterward, these E-textiles are both p-type and n-type doped, using nitrogen plasma treatment to prepare nitrogen-doped graphene as a p-type E-textile and electrochemical deposition of titanium on graphene as n-type Doped E-textiles. This increases the charge carrier density, consequently increasing the conductivity of the graphene. Doping rGO-modified textiles open up a visualization of the p-n junction fully-textile diodes and its further applications.
