Carbon nanotubes (CNT) are tubular carbon fibers at the nano-size level (1 nm = 1/1,000,000 of 1 mm). Carbon is very light compared with metal, yet has greater conductivity, thermal conductivity, hardness, and flexibility than metal. Thus, development has been carried out in this area with the expectation of industrial applications in all types of fields.
Nevertheless, there have been high technical hurdles with regard to eliciting the outstanding features of CNT since attraction between molecules is strong even at nano sizes, and since the fine and long fiber form of CNT easily becomes entangled and ends up strongly aggregating.

 

We have succeeded in developing our own unique technologies for disentangling aggregated CNT. These utilize the outstanding characteristics of CNT and our own unique dispersion technologies. We have succeeded in achieving extensive commercialization in this regard and have been sending out various products in Japan and to overseas.

Introduction of applications

Paints

We have achieved the world’s highest level of film performance regarding resins in terms of rust inhibition, impact resistance, and abrasion resistance. We have already established patents worldwide, and have achieved standardization in Japan under the Japanese Industrial Standards (JIS). Adoption as surface treatment materials has been progressing in relation to chemical plants for oil & gas in harsh environments such as coasts and offshore in Japan and overseas, as well as power-generation infrastructure, ships, and ocean observation equipment. These products dramatically increase the life spans of such structures, so they contribute to ground-breaking energy saving and resource saving.

Fuel cells

We are carrying out research & development to boost the performance of fuel-cell electrodes by utilizing the unique structures of CNT.
The technical issues regarding fuel-cell electrodes are said to be “reducing the volume of catalyst precious metals” and “improving catalyst durability.” We are resolving these issues through CNT modifications based on our patented technologies, and we will thus contribute to expanding the fuel cell market, which is the front runner for next-generation energy.

Composite materials

We are improving the mechanical performance of carbon fiber reinforced plastics (CFRP).
We have achieved excellent dispersion of CNT in CFRP using our own unique technologies, and have thus achieved an approximately 30% improvement in mechanical performance relative to conventional materials. This was realized through joint development together with the incorporated administrative agency the Japan Aerospace Exploration Agency (JAXA).
The adoption of these composite-related technologies, which have been patented, has been progressing centering on sports fields such as bicycles, golf clubs, tennis rackets, and fishing rods. Furthermore, by using the materials as additives in speaker diaphragms, we have succeeded in simultaneously enhancing the previously incompatible elements of acoustic velocity and attenuation performance. There has already been adoption of the materials with regard to automobiles, televisions, and room speakers.
Going forward, based on realizing components that are lighter, thinner, shorter, and smaller through the development of compounds with even higher strength and elasticity, we will reduce environmental loads and aim to contribute to the energy field and high-speed transportation infrastructure.
