Abstract: This review article deals with the recent developments in smart Nano-textiles that have the potential to revolutionize the functionality of clothing and the fabrics in our surroundings. The traditional markets of apparel and home textiles continue to be influenced by nanotechnologies, towards a new direction of value added textiles through finishing and coating using nanomaterials. Nano scale manipulation results in new functionalities for intelligent textiles, including self-cleaning, sensing, actuation and communication. This is achieved by development of new materials, fibers and finishings, Inherently Conducting Polymers (ICP), carbon nanotubes and antimicrobial nano-coatings. These additional functionalities extend their application to various fields like healthcare, sports, military applications and fashion design. With the help of the smart nano-textiles, the wearer and the surrounding environment may be monitored by continuously updating health status of the individual or environmental hazards without making any harm to the wearer. In addition, smart textiles have become a critical part of the body sensor networks that carry out sensing, actuation, control and wireless data transmission. This study reviews current research in nanotechnology applications to textiles, from fiber manipulation and development to end uses of smart nano-textiles.
