Featured productsHigh-dispersion carbon nanotube masterbatches
With their superior electroconductivity, light weight and thermal conductivity, carbon nanotubes are utilized in various automobile parts. However, while hopes are placed on them as “dream materials,” high-precision single-walled carbon nanotubes are highly cost-prohibitive and bear the risk that humans will breathe in minute particles.
Moriroku Chemicals proposes innovate solutions for such challenges.
Overwhelming advantage over existing materials
Examples of things that become possible when adding carbon allotropes such as graphene, graphite and carbon nanotubes (“CNT” below) as functional materials are the flow of electricity in resin with no conductivity and functionality as a heating element when electric resistance is applied. Among carbon allotropes, CNT, which were discovered in the 1990s, are particularly hard to process, and still have numerous areas with room for improvement.
CNT have a string-shaped structure far narrower than a spiderweb, and exist in two configurations: multi-walled carbon nanotubes (“MWNT” below) and their higher-precision counterpart, single-walled carbon nanotubes (“SWNT” below). While MNTW, with their relatively low cost, are mass-produced, they are prone to becoming intertangled like fabric pills, resulting in imbalance when they are incorporated into the likes of resin. This makes it difficult to draw out their theoretical performance.
With CNT masterbatches offered by Moriroku Chemicals, a special manufacturing process is applied to align MWNT in a single direction and disperse them uniformly before incorporating them into resin. The result is innovative materials whose performance favorably compares with SWNT. This allows us to provide CNT in the form of masterbatches that are tailored to customer needs and also feature superior workability and safety.
Additionally, relative to carbon black that is manufactured using the thermal decomposition method and incomplete combustion with oil, natural gas and other hydrocarbons as their raw materials, CNT produced through catalytic reactions emit less CO2 upon manufacture, enabling us to limit our environmental footprint.
Proposed Utilization in Automobile Field 1
Given the multiple superior characteristics of CNT, they have a variety of conceivable applications depending on the ideas behind them. Taking advantage of their high electroconductivity (1,000 times that of copper) opens the door to their potential utilization in power cables and batteries and automobile parts surrounding electrical components.
Proposed Utilization in Automobile Field 2
By taking advantage of their electroconductivity, CNT can be applied to technological areas that involve controlling static electricity, such as electrostatic coating that does not contain primer and static electricity control in room interiors.
Proposed Utilization in Automobile Field 3
Conceivable means of using CNT for the purpose of intercepting electromagnetic waves include their utilization in power cable covering and tubes.
In addition, masterbatches using SWNT supplied by MC demonstrate electroconductivity with just small amounts added. This also makes it possible to realize transparent conductive films. Depending on the ideas behind them, the possibilities for utilization are limitless.
