A Breakthrough Material for the Future! The Potential of Carbon Nanotubes and Moriroku’s Innovative Technology
What Are Carbon Nanotubes (CNTs)—the Dream Material with Extraordinary Properties?
Carbon nanotubes (CNTs) are ultra-thin cylindrical structures made entirely of carbon atoms, with diameters measuring just a few nanometers. This tiny architecture gives rise to astonishing properties.
For example, CNTs are 50 times stronger than steel, have five times the thermal conductivity of copper, and only half the density of aluminum. On top of that, their electrical conductivity can be up to 100 times greater than copper.
In recent years, CNTs have gained attention as conductive additives that enhance the performance of lithium-ion batteries (LiBs), leading to rapid growth in CNT slurry production.

CNT slurry refers to a liquid dispersion of carbon nanotubes, primarily used in the manufacturing of lithium-ion batteries and conductive materials.
Challenges in Harnessing the Full Potential of CNTs
Despite their remarkable properties, carbon nanotubes (CNTs) come with challenges. In particular, relatively low-cost multi-walled CNTs (MWCNTs) tend to form tangled, “ball-like” clusters due to their fine fibrous structure, making uniform dispersion extremely difficult.
When mixed directly into resin, CNTs often become unevenly distributed, preventing their exceptional performance from being fully realized. This has been a key reason why CNTs have not seen widespread use in compound materials such as plastics.
Moriroku’s Breakthrough: “High-Dispersion Carbon Nanotube (CNT) Masterbatch”
Moriroku has developed a groundbreaking technology that addresses a long-standing challenge in CNT utilization.
In collaboration with domestic partner companies, we have devised a proprietary method to untangle the clustered, ball-like multi-walled CNTs (MWCNTs), eliminating agglomeration. These disentangled CNTs are then uniformly dispersed into resin and offered as pelletized “High-Dispersion CNT Masterbatch.”
This innovation unlocks the full potential of MWCNTs, enabling performance comparable to single-walled CNTs (SWCNTs) while maintaining cost-efficiency. It also preserves the physical properties of the base resin.
