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.

Another nano consumer product gets negative attention in Germany

The discussion about the health scare caused by the Magic-Nano sealing spray (which, as it turned out, was neither magic nor nano - see this article) has barely ebbed when questions about another nano consumer product arise. This time, it is not a health scare but rather the opposite - alleged health benefits of nanoparticles.

Nanoparticles and sunscreen safety

The use of nanoparticles in sunscreens is one of the most common uses of nanotechnology in consumer products. Well over 300 sunscreens on the market today contain zinc oxide or titanium oxide nanoparticles.

Electrochromic devices based on tungsten oxide

An electrochromic display is one of the most attractive candidates for paper-like displays, so called electronic paper, which will be the next generation display, owing to attributes such as thin and flexible materials, low-power consumption, and fast switching times.

Making Nanotube TVs happen

Researchers have turned to carbon nanotubes to create a new class of large area, high resolution, low cost flat panel displays. Some believe field emission display (FED) technology, utilizing carbon nanotubes (CNT) as electron emitter, will be the biggest threat to LCD's dominance in the panel display arena.
