In this work we study the mechanical properties and failure mechanism of nanocomposites made of graphene oxide sheets embedded in polymeric systems, namely films and electro-spun nanofibers. In this last system, contrary to conventional bulk composites, the size of the nano-reinforcement (GO sheets) is comparable to the size of the nanofibers to be reinforced (≈ 200 nm). As an ideal polymeric matrix we use gelatin.We demonstrate that the high chemical affinity of the two materials hinders the renaturation of gelatin into collagen and causes a nearly ideal mixing in the GO-gelatin composite. Adding just 1% of GO we obtain an increase of Young's modulus >50% and an increase of fracture stress >60%. We use numerical simulations to study the failure mechanism of the fibers. Calculations agree very well with experimental data and show that, even if cracks start at GO sheet edges due to stress concentrations, crack propagation is hindered by the nonlinear behaviour of the matrix. As an additional advantage, the presence of the GO sheets in continuous gelatin films improves the material stability to phosphate buffer solutions from 2 days to 2 weeks, making it a better material than gelatin for applications in biological environments.4

“…A completely new collector was designed that yielded a pressure-driven, localized cotton-wool structure in free space, from which high strength and continuous yarns were drawn. The fabrication of conductive, flexible, and durable textiles with reduced graphene oxide (RGO) on nylon-6 yarns, cotton yarns, polyester yarns, and nonwoven textile fabrics via a facile preparation method has been reported recently by Prof. Byung Hoon Kim's group [55]. They also solved the problem of adhesion between GO and textiles using bovine serum albumin (BSA) proteins, which serve as universal adhesives for any textile, regardless of their surface conditions.…”

E-textiles (electronic textiles) are fabrics that possesses electronic counterparts and electrical interconnects knitted into them, offering flexibility, stretchability, and a characteristic length scale that cannot be accomplished using other electronic manufacturing methods currently available. However, knitting is only one of the technologies in e-Textile integration. Other technologies, such as sewing, embroidery, and even single fiber-based manufacture technology, are widely employed in next-generation e-textiles. Components and interconnections are barely visible since they are connected intrinsically to soft fabrics that have attracted the attention of those in the fashion and textile industries. These textiles can effortlessly acclimatize themselves to the fast-changing wearable electronic markets with digital, computational, energy storage, and sensing requirements of any specific application. This mini-review focuses on recent advances in the field of e-textiles and focuses particularly on the materials and their functionalities.

Graphene has emerged as a revolutionary material in different fields of science and engineering due to its extraordinary properties such as: high electron mobility, high thermal conductivity, mechanical properties, easy functionalization, etc. The field of textiles is continuously integrating new materials to provide fabrics with new functionalities, hence its incorporation on fabrics was a logical step. Its application to the field of textiles has been recently reported, which has allowed the development of textiles with different functionalities such as: antistatic, UV-protecting, electroconductive, photocatalytic, antibacterial, energy storage in supercapacitors, electrodes for batteries, thermal conductivity, sensors, etc. Up to date no review has been written regarding graphene-based fabrics and their applications. The present review aims to fill the existing gap and provide perspectives into the preparation and applications of graphene-based fabrics and yarns.
