CNT conductive material paste dispersion system

CNT dispersion is determined by the process. Control of aggregation stabilizes conductivity.

In conductive paste using CNT (carbon nanotubes), the strength of aggregation and the difficulty of dispersion are challenges. If not sufficiently dispersed, a conductive network will not form, leading to unstable performance; on the other hand, excessive shear can lead to the destruction of the CNT structure, making the optimization of dispersion conditions essential. Furthermore, even slight differences in the dispersion state can significantly affect viscosity and conductivity, becoming a factor in quality variation during mass production. This system appropriately breaks down CNT aggregation while maintaining structure through process design that includes powder input, wetting processes, dispersion energy control, and circulation conditions. It is designed with the same logic from the lab to mass production, achieving a balance between conductivity and reproducibility.

basic information

A solid-liquid mixing dispersion system specialized for CNT conductive material dispersion. It optimizes dispersion energy (shear force) and residence time according to the aggregation characteristics, length distribution, binder type, solvent conditions, and concentration of CNTs, achieving uniform dispersion while preventing structural damage due to over-dispersion. The processes of pre-mixing, wetting, dispersion, and circulation homogenization are integrated into a single design. It supports inline processing, circulation processing, and batch processing, allowing for configuration proposals tailored to specific applications. In addition to selecting equipment including high-shear dispersion devices (such as IKA), it also addresses powder supply, piping design, CIP, and data management. A consistent scale-up design is provided from lab equipment to mass production lines.
