Surface Functionalization of Multi-Walled Carbon nanotubes and Applications

  • April 25,2024.
Multi-walled carbon nanotubes (MWCNTs) exhibit exceptional strength, unique metallic or semiconductor conductivity, hydrogen storage capability, adsorption capacity, strong microwave absorption, making them the material of choice for various high-tech applications in aerospace, aviation, electronics, and mechanical engineering. The main challenges hindering the widespread application of carbon nanotubes are their dispersibility and compatibility with matrix materials, which can be addressed through surface functionalization of the carbon nanotubes. Surface functionalization of carbon nanotubes involves introducing functional groups onto their surfaces to enhance their solubility, dispersibility, and compatibility with other materials. Here are some common surface functionalization methods for MWCNTs and their applications:

1. Carboxylation: Introducing carboxyl (-COOH) functional groups onto the surface of MWCNTs enhances their solubility, dispersibility, and compatibility with catalyst supports, biosensors, drug delivery systems, and the preparation of functional composite materials.

2. Hydroxylation: Introducing hydroxyl (-OH) functional groups onto the surface of MWCNTs improves their solubility and compatibility with aqueous systems. Hydroxylated MWNTs find wide applications in biomedical fields such as bioimaging, drug delivery, cell culture, and tissue engineering.

3. Amination MWCNTs: Introducing amino (-NH2) functional groups onto the surface of MWCNTs imparts amine-like characteristics. Aminated MWNTs are extensively utilized in biosensors, catalysis, electrocatalysis, and electronic devices.

4. Nickel plated MWCNTs: Coating the surface of MWCNTs with a layer of nickel (Ni) nanoparticles enhances their conductivity and thermal stability, enabling broader applications in electronic devices, sensors, and catalysis.

5. Graphitization: Subjecting MWCNTs to high-temperature treatment transforms their structure into a more graphite-like form, known as graphitized MWCNTs. Graphitized MWCNTs exhibit excellent conductivity and mechanical properties, making them suitable for applications in conductive materials, composite materials, and supercapacitors.

In summary, the surface functionalization of MWCNTs offers a versatile approach to tailor their properties and expand their applications across a wide range of industries and fields.
