Graphene Modified Cotton Textiles

Abstract

The graphene oxides are abundant in hydroxyl and carboxyl groups that are close to the reactive dyes. These structural features gave a possibility to modify textiles to enhance the conductivity by using the dyeing and finishing method. Herein, graphene modified cotton textiles are fabricated by soaking cotton cloth in graphene oxide colloid. After reduction, the modified textiles exhibit an improved conductivity. The present work contributed a facile strategy for graphene modified textiles.

Chemical and electrochemical study of fabrics coated with reduced graphene oxide

“…Fugetsu et al [22] reported resistance values ranging from 10 2 to 10 9 Ω/cm depending on the RGO content for the deposition of RGO on polyarylate. Gu et al [23] obtained resistances of 2.01·10 7 Ω for one coating process of RGO on cotton fabrics. The necessity of more coating processes to achieve low resistances in the case of employing graphene sheets [21] could be explained by the low adhesion of graphene on polyester fabrics due to the low presence of polar groups on graphene sheets.…”

“…Regarding conducting fabrics coated with graphene and its derivatives very little has been reported [21][22][23]. Yu et al deposited graphene directly on the fabrics and later electrodeposited MnO 2 to produce supercapacitors [21].…”

“…Yu et al deposited graphene directly on the fabrics and later electrodeposited MnO 2 to produce supercapacitors [21]. Other strategy employed is to adsorb graphene oxide (GO) sheets on the surface of the fabric and later reduce them employing chemicals such as hydrosulfite [22] or hydrazine [23]. Graphene oxide sheets are adsorbed on the surface of the fabric due to the attraction forces existing between the functional groups of the fabrics and the oxidized groups of graphene oxide sheets.…”

Electrochemical characterization of reduced graphene oxide-coated polyester fabrics

“…The process is similar to a dying process where an adsorption process occurs [16]. Once the fabric is coated with GO, it is then reduced to RGO using reducing agents such as sodium hydrosulfite [16], hydrazine [17], etc. GO coated fabrics have also generated interest due to the photo-catalytic activity of GO and also to its antibacterial activity [18].…”

“…Graphene-coated fabrics have usually been obtained by placing the fabrics in contact with solutions containing GO [16,17]. GO sheets are adsorbed on the surface of the fabrics due to the attraction forces between the functional groups of the fabrics and the oxidized groups of the GO sheets.…”
