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.

Bast fiber-reinforced polymer composites (BFRPs) are grabbing considerable research attention due to their assertive impact on the environment and excellence in biodegradability. Though BFRPs have excellent ecological performance factors, they also lack in some cases, such as lower mechanical, electrical, and thermal properties, due to the significant moisture absorption, minimal thermal stability, and inherent nature of bast fibers. BFRPs exhibit weaker fiber/matrix interfacial adhesion as compared to synthetic fiber-reinforced polymer composites, resulting in lower mechanical properties. Nowadays, a wide variety of fiber and matrix modification techniques are practiced improving the fiber-matrix interaction, which ultimately improves the mechanical properties. Among the fiber and matrix modification techniques, nanofiller integration is the most promising one. This study reviews the impacts of introducing carbon-based nanofillers, particularly graphene and carbon nanotubes (CNT), in diversified BFRPs. The influence of carbon-based nanofillers on the mechanical, electrical, and thermal behavior of BFRPs and their potential prospects are comprehensively reviewed. The paper concludes with the challenges and difficulties in composite processing, along with the techniques for overcoming them.
