  • Description
  • Additional information

                          Carbon nanotube (CNT) powder is a fine, solid form of carbon nanotubes—cylindrical nanostructures made of rolled graphene sheets. It is widely used in research and industry as a high-performance additive to enhance the electrical conductivitythermal stability, and mechanical strength of various materials.

Key Material Properties:

CNT powder possesses unique physical characteristics:

  • Exceptional Strength: Tensile strength can reach 40–100 GPa, making them significantly stronger than steel while being much lighter.
  • High Conductivity: They are excellent conductors of heat and electricity, with thermal conductivity near 3,500 Wm⁻¹K⁻¹ at room temperature.
  • High Aspect Ratio: Lengths can reach micrometers or even millimeters while diameters remain in the nanometer range, facilitating the creation of reinforcing networks in host materials.
  • Large Surface Area: Provides significant space for chemical interactions, which is critical for energy storage and catalytic applications. 

Major Industrial Applications:

  • Energy Storage: Used in lithium-ion battery electrodes to improve charge capacity and cycle life.
  • Advanced Composites: Added to polymers and metals (like aluminum) to increase durability, toughness, and anti-static properties.
  • Sensors: Integrated into platforms for highly sensitive gas sensing (e.g., NO₂, NH₃) and biomedical diagnostics.
  • Coatings & Textiles: Imparts permanent conductivity to industrial coatings and strength to smart textiles or protective armor.

Lorem ipsum dolor sit amet, cibo mundi ea duo, vim exerci phaedrum. There are many variations of passages of Lorem Ipsum available, but the majority have alteration in some injected or words which don't look even slightly believable. If you are going to use a passage of Lorem Ipsum, you need to be sure there isn't anything embarrang hidden in the middle of text.

It has survived not only five centuries, but also the leap into electronic typesetting unchanged. It was popularised in the sheets containing lorem ipsum is simply free text.
