Carbon Nanotube Paste

What is Carbon Nanotube Paste?

Carbon nanotube paste, often referred to as CNT conductive paste, is a next‑generation material designed to deliver superior electrical conductivity and mechanical robustness. It is formulated by dispersing multi‑walled carbon nanotubes (MWCNTs) in a water‑based or solvent‑based medium, combined with small amounts of additives. This composition enables the formation of highly efficient conductive networks, making CNT paste a versatile solution for advanced electronics, energy storage, and sensor technologies. Its unique properties—high aspect ratio, large surface area, and ultra‑low resistivity—position CNT paste as a powerful alternative to traditional conductive additives such as carbon black, graphite, and carbon fiber. By enhancing both electrical and structural performance, it has become a critical material in modern high‑tech manufacturing.

How to Use Carbon Nanotube Paste?

Before application, ensure the substrate surface is clean and dry. Stir the paste thoroughly to achieve uniform dispersion of CNTs. For coating methods such as doctor‑blade, slot‑die, or spray coating, the paste can be applied directly or diluted depending on process requirements. After deposition, allow the coating to dry under ambient conditions or mild heating to achieve a uniform conductive layer. The controlled viscosity of CNT paste ensures smooth processing across various printing and coating techniques.

Applications of Carbon Nanotube Paste

Carbon nanotube paste offers versatile applications across industries, from lithium‑ion battery electrodes—where it boosts conductivity in LFP, LCO, NCM, LMN, and graphite for higher capacity, lower resistance, and longer cycle life—to flexible electronics on PET and PI substrates, sensors with enhanced signal accuracy, conductive coatings and EMI shielding on glass, plastics, and polymers, and printed circuits and microelectronics via inkjet, screen printing, and roll‑to‑roll processes, all supported by its eco‑friendly water‑based formulation.
