Differential functional finishes for textiles using graphene oxide

Abstract

Purpose Graphene, which has abundant availability in nature, is currently under research for its functional applications in the field of textiles. The sp2 Hybridized 1-atom-thick planar sheet has been under consideration for its unique electrical, mechanical and thermal properties, but there exists a void for aggregated data on the findings of other co-functional properties attained by the material using graphene oxide (GO) finish. This paper aims to define the techniques of extraction of GO, method of its application on textile material followed by detailed evaluation of the differential functional properties achieved. Design/methodology/approach The methodology used to explain the multiple functionalities of GO finish have been carried out by starting with the chemistry of graphene and the isolation of GO from graphite, followed by the techniques for its application on the textile along with the study on the induced functional properties that may aid to increase its potential applications. Findings It has been observed that with the aid of optimization of GO finish, the finish in lieu with the conductive potentialities may further provide with many essential properties such as hydrophobicity, ultraviolet protection and antibacterial property. Originality/value The field of research on GO finish is naive and except few properties, many functionalities are still unexplored that may enable its smooth production, handling and expanding its area of application. The agglomeration of scattered findings on the achievable functional properties of GO on various textiles has been achieved in this paper.

Electrical resistivity and thermal conductivity properties of graphene‐coated woven fabrics

“…The general methods of improving thermal transfer are to adjust fabric thickness, porosity, fabric structure and density, and better results can be achieved with the help of coating techniques. The graphene‐coated textiles exhibit significant multifunctional properties, and one of them is high thermal conductivity …”

The fabrication of a graphene and conductive polymer nanocomposite-coated highly flexible and washable woven thermoelectric nanogenerator

“…[30] Even though, the fabrication of graphene-based thermoelectric devices is not much complex and challenging; as compared to other inorganic materials, which need critical care and consideration during processing. [31] The processes include chemical, and thermal reduction of GO into rGO. [32] Although, the chemical reduction of GO is generally achieved with strong reducing agents; including hydrazine hydrate (H.H), hydro Iodic (H.I), sodium borohydrate (NaBH 4 ).…”

Improving durability and electrical performance of flexible printed e-textile conductors via domestic ironing

“…E-textiles research presents a pathway for combining such electronic functionality with textiles of different materials (natural/synthetic or organic/inorganic fibres) [4][5][6], structures (knitted, wovens and nonwovens, calendered, etc) [7][8][9][10][11], and surface finish [12][13][14] while preserving the inherent physical properties that made textiles desirable and versatile materials. So far, the research literature shows that e-textiles are produced by fusing a variety of functional materials such as electrically conductive films [15,16], piezoelectric films [17,18], and thermo/photochromic films [19] with the textiles using any or a combination of (a) rapid prototyping and additive manufacturing processes such as 3D printing [20], ink-jet printing [21], spray-coating [22] and dispenser printing [23] for low-throughput manufacturing, (b) microfabrication processes based on thin-film materials [24], and flexible 1D filaments/yarns [25] and, (c) traditional manufacturing processes within the textile industry (e.g.…”
