Nickel-coated multi-walled carbon nanotubes (MWCNTs) offer enhanced conductivity, optimized magnetic properties, and superior mechanical reinforcement. Designed for advanced material applications, they ensure efficient electron transport, extended durability, and functional adaptability.
Product Overview
Nickel-coated multi-walled carbon nanotubes (MWCNTs) are composite materials made of carbon nanotubes and nickel, with nickel uniformly coated on the surface of the nanotubes. Multi-walled carbon nanotubes exhibit extremely high axial tensile strength, elastic modulus, low density, good chemical stability, and excellent high-temperature resistance. While carbon nanotubes themselves are relatively inert, the ultrasound dispersion and surface nickel plating significantly enhance their dispersibility and surface activity. This makes nickel-coated carbon nanotubes highly dispersible in metal matrices, further improving their performance as reinforcement materials for metal matrix composites.
Key Features
- High Catalytic Activity: Nickel nanoparticles serve as active centers for catalysis, enabling the nanotubes to catalyze a variety of chemical reactions. The catalytic activity is significantly enhanced by the support provided by the multi-walled carbon nanotubes.
- Stability and Dispersibility: The synergistic effect of the carbon nanotube structure helps prevent the aggregation and deactivation of nickel nanoparticles, thus extending the lifespan of the catalyst.
- High Conductivity: Nickel-coated carbon nanotubes exhibit excellent electrical conductivity, with the addition of nickel further improving their conductivity, making them ideal for electrochemical applications.
Applications
- Energy Sector: Used as electrode materials in lithium-ion batteries, supercapacitors, and other energy storage devices, enhancing energy storage performance.
- Catalysis: Applied as highly efficient catalysts for environmental protection, such as in exhaust gas purification and water pollution treatment.
- Electronics: Used to manufacture high-performance composite materials for electronic devices, integrated circuits, and other advanced technologies.
- Biomedicine: Applied in biosensors, drug delivery, and tissue engineering, advancing biomedical technology.
- Other Industries: Potential applications in aerospace, automotive, and environmental protection sectors.
