Features
Structural Features
Multiple Graphene Layers: MWCNTs water dispersion consist of two or more concentric graphene tubes rolled around each other. Each layer of graphene is arranged in a hexagonal lattice. The number of layers can vary from a few (bi-walled) to several tens of layers (multi-walled).
Diameter and Length: MWCNTs water dispersion typically have diameters ranging from 1 nm to 100 nm and can be several micrometers to millimeters in length. The length-to-diameter ratio is extremely high, making them ideal for various structural and electronic applications.
Hollow Structure: The central part of the nanotube is hollow, which allows MWCNTs to act as channels for molecular or ionic transport. This unique feature has applications in energy storage, sensing, and drug delivery.
Mechanical Properties
High Tensile Strength: MWCNTs exhibit extraordinary tensile strength due to the strong carbon-carbon bonds in their structure. Their tensile strength can reach over 100 times that of steel, making them ideal candidates for reinforcement in composite materials.
Flexibility and Elasticity: Despite their high strength, MWCNTs are highly flexible and can bend without breaking. This flexibility allows them to be integrated into a variety of materials, such as flexible electronics and smart fabrics.
High Stiffness: MWCNTs are extremely stiff, meaning they can support heavy loads without deforming, making them useful for structural and engineering applications.
Electrical Properties
Exceptional Electrical Conductivity: MWCNTs have excellent electrical conductivity, similar to or even surpassing that of metals like copper. The electrical conductivity is attributed to the delocalized electrons in the graphene sheets, allowing for efficient charge transport.
Metallic or Semiconducting Behavior: Depending on their structure and how they are processed, MWCNTs can exhibit either metallic or semiconducting behavior, which makes them versatile for use in various electronic devices and sensors.
Surface Conductivity: The surface of MWCNTs also allows for the effective conduction of electrical signals, which is beneficial in sensor applications and nanoelectronics.
