Chemi Tech: Overcoming Carbon Nanotube Dispersion Challenges, Unlocking Ultimate Material Performance

In advanced composite materials, electronic devices, and new energy fields, carbon nanotubes (CNTs) hold great promise due to their exceptional electrical conductivity, thermal conductivity, and mechanical properties. However, in practical applications, CNTs are prone to agglomerate into bundles due to van der Waals forces, making uniform dispersion within a matrix extremely difficult. This not only results in material performance far below theoretical values and waste of expensive nanomaterials but also leads to poor process stability and low product yield, presenting a common challenge for many R&D and production teams.

Chemi Tech has deeply understood this core pain point. Leveraging profound expertise in nanomaterial surface modification, we have developed a series of high-performance carbon nanotube dispersants. Our solution is not merely about adding an auxiliary agent. It involves precise molecular design, enabling the dispersant molecules to anchor firmly onto the CNT surface, creating a stable steric or electrostatic repulsion barrier that fundamentally prevents re-agglomeration.

Our recommended step-by-step solution is clear and easy to implement: Step 1, Diagnostic Analysis. Our technical team will collaborate with you to analyze your CNT type, target system, and performance requirements. Step 2, Customized Formulation. Based on the diagnosis, we will select or compound the most suitable Chemi Tech dispersant grade for you. Step 3, Process Optimization. We provide detailed dispersion process guidance, including recommended addition sequence, shear force intensity, duration, and other key parameters. Step 4, Result Verification. We assist in evaluating the dispersed slurry through particle size analysis, stability testing, and final composite material performance assessment to ensure desired outcomes are achieved.

For instance, a team focused on flexible sensing material development struggled with uneven CNT dispersion in polymers, leading to unstable sensor signal response and significant batch-to-batch variation. After adopting the customized dispersant and supporting process provided by Chemi Tech, the stability of their CNT slurry improved markedly, showing no sedimentation after one week of standing. The resulting film material exhibited a uniform conductive network, with batch consistency in electrical performance increasing by over 70%, successfully facilitating the finalization and mass production of their new product.

Choosing Chemi Tech means you not only acquire a high-performance dispersant but also gain a technical partner dedicated to solving nanomaterial application bottlenecks. Let us help you translate the extraordinary potential of carbon nanotubes into your product's core competitive edge.
