Market Overview and Drivers
CNTs are broadly categorized into Single-Walled Carbon Nanotubes (SWCNTs) and Multi-Walled Carbon Nanotubes (MWCNTs). While SWCNTs offer superior electronic properties, MWCNTs are more cost-effective to produce and are widely used in commercial applications requiring enhanced mechanical strength and conductivity.
The versatility of CNTs has led to their adoption in numerous high-growth sectors:
Electronics: As conductive additives in touchscreens, flexible displays, and advanced sensors; components in transistors and interconnects.
Automotive: For lightweight composites, enhanced battery performance, and conductive plastics.
Energy: In high-performance batteries (lithium-ion, solid-state), fuel cells, and supercapacitors for improved energy storage and efficiency.
Aerospace Defense: For lightweight, high-strength composites used in aircraft structures and ballistic protection.
Sports Equipment: Enhancing durability and performance in items like bicycles, tennis rackets, and golf clubs.
Medical: In drug delivery systems, biosensors, and tissue engineering.
Key drivers stimulating market expansion include:
Miniaturization of Electronics: The demand for smaller, more powerful electronic devices requires materials with superior conductivity and strength.
