Teijin is a Japanese chemical and pharmaceutical company known to me due to its production of nanotechnology-enabled fibres. As a consequence, a Jan. 21, 2016 news item on Nanotechnology Now piqued by interest,
Teijin Limited announced today that it will exhibit a wide range of nanotech materials and products incorporating advanced Teijin technologies during the International Nanotechnology Exhibition and Conference (nano tech 2016), the world’s largest nanotechnology show, at Tokyo Big Sight in Tokyo, Japan from January 27 to 29 .
A Jan. 21, 2016 Teijin news release, which originated the news item, offers further detail,
Teijin’s booth (Stand 4E-09) will present nanotech materials and products for sustainable transportation, information and electronics, safety and protection, environment and energy, and healthcare, including the following:
– Nanofront, an ultra-fine polyester fiber with an unprecedented diameter of just 700 nanometers, features slip-resistance, heat shielding, wiping and filtering properties. It is used for diverse applications, including sportswear, cosmetics and industrial applications such as filters and heat-shielding sheets.
– Carbon nanotube yarn (CNTy) is 100%-CNT continuous yarn offering high electrical and thermal conductivity, easy handling and flexibility. Uses including space, aerospace, medical and wearable devices are envisioned. A motor using CNTy as its coil, developed by Finnish Lappeenranta University of Technology Opening a new window, will be exhibited first time in Japan.
– NanoGram Si paste is a printed electronics material containing 20nm-diameter silicon nanoparticles for photovoltaic cells capable of high conversion efficiency.
– Teijin Tetoron multilayer film is a structurally colored multilayer polyester film that utilizes the interference of each multilayer’s optical path difference rather than dyes or pigments. Decorative films for automotive and other applications will be exhibited.
– High-performance membranes, including a high-precision porous thin polyethylene membrane and multilayer membrane composites for micro filters, are moisture-permeable waterproof sheets.
– Carbon Alloy Catalyst (CAC) (under development) is platinum free catalyst made from polyacrylonitrile (precursor of carbon fiber) in combination with iron species, which is less expensive and more readily available than platinum, enabling production for reduced cost and in higher volumes. Fuel cells in which the cathode consists of the CAC without the platinum catalyst can generate exceptionally high electric power.
– Carbon nanofiber (under development) is a highly conductive carbon nanofiber with an elliptical cross section consisting of well-developed graphite layers ordered in a single direction. Envisioned applications include additives for lithiumion secondary batteries (LIBs) , thermal conducting materials and plastic-reinforcing materials, among others.
Teijin first came to my attention in 2010 with their Morphotex product, a fabric based on the nanostructures found on the Blue Morpho butterfly’s wing. I updated the story in an April 12, 2012 posting sadly noting that Morphotex was no longer available.
