Abstract [en]

Textiles with electrical properties, known as e-textiles, are realized by different methods. Among these, graphene-coated textiles have attracted great attention due to its multifunctional properties such as being flexible lightweight; and offering interesting optical and electrical properties. While Aqueous dispersion of graphene oxide (GO) could be prepared and applied as a dye to textiles via a simple and cost-effectivene dip-coating method. Moreover, the GO could be reduced to graphene directly on the surface of the textiles. However, the GO flakes do not adhere properly to most textiles at any pH values probably because of electrostatic repulsion between the particles and the textile substrate as both the aqueous solution of GO and most textiles carry negative surface charges. Though, GO flakes could be easily assembled on a positively charged surface. Therefore, textiles need to be cationized before the dip-coating in the GO dispersion. In this work a number of both organic and inorganic cationic agents such as chitosan, Poly(diallyldimethylammonium chloride), Hexadecylpyridinium chloride, and Polyethylenimine are applied to the textiles before the coating process. Further on the so formed systems are characterized by scanning electron microscopy, FT-IR measurement, four-terminal sensing surface resistance measurement, diffusion reflection spectroscopy, electro-thermal analysis, and electro-mechanical analysis. The results display the fact that utilizing an appropriate cationic agent not only enhances the absorption of GO onto the textile surfaces but also play a critical role for the electrical conductivities and electro-thermal properties of the coated fabrics, with values varying between 12 to 0.6 kΩ.cm-1.
