Fabricating e-textiles with reduced graphene oxide

electronic_textileThe future of your clothes will be electronic. Not only will electronic devices be embedded on textile substrates, but an electronics device or system could become the fabric itself. These electronic textiles will have the revolutionary ability to sense, compute, store, emit, and move - think biomedical monitoring functions or new man-machine interfaces, not to mention game controllers - while leveraging an existing low-cost textile manufacturing infrastructure. In new work, a group of scientists from Korea have now reported novel method for the fabrication of conductive, flexible, and durable graphene textiles wrapped with reduced graphene oxide.

Nanotechnology textiles

cloth_rolls'Nano Textiles' can be produced by a variety of methods. The key difference among them is whether synthetic nanoparticles are integrated into the fibres or the textile, or are applied as a coating on the surface, and/or whether nanoparticles are added to the nanoscale fibres or coating. This article clarifies nano-textile manufacturing processes and application areas, and gives an overview about the potential effects on the environment and health. Many questions remain unanswered, however, there is a need for considerably more research not only for product development but also into the usefulness and risks which nano-textiles give rise to. The open questions have prompted the Swiss Textile Federation to undertake a joint project with the Swiss Federal Laboratories for Materials Science and Technology (EMPA) entitled 'Nanosafe Textiles' and to initiate discussions on the topic.

Nanotechnology improves wool fabrics

superhydrophilic_wool_fabricsNanotechnology shows great potential for revolutionizing the textile industry across its entire range of applications with its ability to impart new functionality to textiles while at the same time maintaining their look and feel. The wool textile industry, for example, is researching the development of textiles with fast-absorbing and quick-drying properties. This has great importance for improving clothing thermophysiological comfort and wearing performance by adjusting the transport of heat and moisture through a fabric which was usually achieved using synthetic fibers. One stubborn hurdle that prevents nanotechnology-enabled 'smart' textiles from becoming more of a commercial reality is the insufficient durability of nanocoatings on textile fibers or the stability of various properties endowed by nanoparticles. Quite simply put, the 'smart' comes off during washing. Developing an effective approach to enhance the coalesce force between nanoparticles and wool fibers has great significance both in scientific and real applications of nanotechnology functionalized textiles.

Nanotechnology e-textiles for biomonitoring and wearable electronics

carbon_nanotube_cottonIf current research is an indicator, wearable electronics will go far beyond just very small electronic devices or wearable, flexible computers. Not only will these devices be embedded in textile substrates but an electronics device or system could ultimately become the fabric itself. Electronic textiles (e-textiles) will allow the design and production of a new generation of garments with distributed sensors and electronic functions. Such e-textiles will have the revolutionary ability to sense, act, store, emit, and move - think biomedical monitoring functions or new man-machine interfaces - while ideally leveraging an existing low-cost textile manufacturing infrastructure. A recent research report proposes to make conductive, carbon nanotube-modified cotton yarn. This would offer a uniquely simple yet remarkably functional solution for smart textiles - close in feel and handling to normal fabric - yet with many parameters exceeding existing solutions.

Woven logic from organic electronic fibers

In the future, wearable electronics will go far beyond just very small electronic devices. Not only will such devices be embedded on textile substrates, but an electronics device or system could become the fabric itself. Electronics textiles will allow the design and production of a new generation of garments with distributed sensors and electronic functions. Such e-textiles will have the revolutionary ability to sense, act, store, emit, and move (think biomedical monitoring functions or new man-machine interfaces) while leveraging an existing low-cost textile manufacturing infrastructure. Reporting a novel approach through the construction of all-organic wire electrochemical transistor devices (WECT) , researchers in Sweden show that textile monofilaments can be coated with continuous thin films of a conducting polymer and used to create microscale WECTs on single fibers. They also demonstrate inverters and multiplexers for digital logic. This opens an avenue for three-dimensional polymer micro-electronics, where large-scale circuits can be designed and integrated directly into the three-dimensional structure of woven fibers.

Textile transistors to create truly wearable electronics

If current research is an indicator, wearable electronics will go far beyond just very small electronic devices. Not only will such devices be embedded on textile substrates, but an electronics device or system could become the fabric itself. Electronics textiles will allow the design and production of a new generation of garments with distributed sensors and electronic functions. Such e-textiles will have the revolutionary ability to sense, act, store, emit, and move (think biomedical monitoring functions or new man-machine interfaces) while leveraging an existing low-cost textile manufacturing infrastructure. Today, only a few steps towards new architectural possibilities of realizing circuit topologies that can be implemented with textile technique have been made: one an example of nonplanar devices and one of textile based devices. Researchers in Italy have now developed an organic field effect transistor (OFET) fully compatible with textile processing techniques.

Nanofinishing in textiles

With the advent of nanoscience and technology, a new area has developed in the area of textile finishing called "Nanofinishing". Growing awareness of health and hygiene has increased the demand for bioactive or antimicrobial and UV-protecting textiles. Coating the surface of textiles and clothing with nanoparticles is an approach to the production of highly active surfaces to have UV blocking, antimicrobial, flame retardant, water repellant and self-cleaning properties. While antimicrobial properties are exerted by nano-silver, UV blocking, self-cleaning and flame-retardant properties are imparted by nano-metal oxide coatings. Zinc oxide (ZnO) nanoparticles embedded in polymer matrices like soluble starch are a good example of functional nanostructures with potential for applications such as UV-protection ability in textiles and sunscreens, and antibacterial finishes in medical textiles and inner wears.
