Electronic textiles (e‐textiles) have drawn significant attention from the scientific and engineering community as lightweight and comfortable next‐generation wearable devices due to their ability to interface with the human body, and continuously monitor, collect, and communicate various physiological parameters. However, one of the major challenges for the commercialization and further growth of e‐textiles is the lack of compatible power supply units. Thin and flexible supercapacitors (SCs), among various energy storage systems, are gaining consideration due to their salient features including excellent lifetime, lightweight, and high‐power density. Textile‐based SCs are thus an exciting energy storage solution to power smart gadgets integrated into clothing. Here, materials, fabrications, and characterization strategies for textile‐based SCs are reviewed. The recent progress of textile‐based SCs is then summarized in terms of their electrochemical performances, followed by the discussion on key parameters for their wearable electronics applications, including washability, flexibility, and scalability. Finally, the perspectives on their research and technological prospects to facilitate an essential step towards moving from laboratory‐based flexible and wearable SCs to industrial‐scale mass production are presented.

Nanotechnology embodies a groundbreaking innovation for the textile and apparel industry, facilitating enhancements to the functionality and performance of textiles, including durability, resistance to water, odor, flame, stain, UV‐protection, and antimicrobial properties. Nanotechnology also enables biosensing, drug delivery, energy generation, and storage in textiles. Here, we present a comprehensive overview of the possibilities offered by nanotechnology in the context of high‐performance textiles providing a roadmap for future research and development in this exciting field. We scrutinize the current research on nanotechnology in textiles, exploring various types of nanomaterials and their properties, the methods of incorporating nanomaterials into textiles, and the numerous applications of high‐performance textiles across critical industries such as healthcare, military, sports, fashion, and wearable electronics. We conclude the review with an analysis of the potential health and environmental concerns arising from the use of nanotechnology in textiles, emphasizing the importance of further research in these areas.

Natural fiber reinforced composites (FRC) are of great interests, because of their biodegradability, recyclability, and environmental benefits over synthetic FRC. Natural jute FRC could provide an environmentally sustainable, light weight, and cost-effective alternative to synthetic FRC. However, the application of natural jute FRC is limited because of their poor mechanical and interfacial properties. Graphene and its derivatives could potentially be applied to modify jute fiber surface for manufacturing natural FRC with excellent mechanical properties, and lower environmental impacts. Here, we review the physical and chemical treatments, and graphene-based modifications of jute fibers, and their effect on mechanical properties of jute FRC. We introduce jute fiber structure, chemical compositions, and their potential applications first. We then provide an overview of various surface treatments used to improve mechanical properties of jute FRC. We discuss and compare various graphene derivative-based surface modifications of jute fibers, and their impact on the performance of FRC. Finally, we provide our future perspective on graphene-based jute fibers research to enable next generation strong and sustainable FRC for high performance engineering applications without conferring environmental problems.
