Single-Walled Carbon Nanotubes

BCGT-1001

GT-1001 is a single-walled carbon nanotube with a narrow diameter distribution of 1-3 nm, few defects, and high uniformity. Its structure is closer to an ideal one-dimensional nanomaterial. High conductivity, theoretically second only to superconductors, can construct a strong long-range conductive network between electrode materials, with minimal energy loss during electron transmission.

GT-1001 has ultra-high flexibility and mechanical properties, and can withstand large stresses and strains without fracture; Having a larger specific surface area can provide more active sites; High thermal conductivity helps with heat dissipation; Due to its excellent conductivity and other properties, it can be 1/10-1/100 of the amount of multi walled carbon nanotubes added, with very small amounts being particularly prominent in colorless applications.

Introduction:

Single walled carbon nanotubes (SWCNTs or SWNTs) are entirely composed of carbon atoms, and their geometric structure can be regarded as a single layer of graphene curled up. The structure determines the properties, therefore, single-walled carbon nanotubes have excellent electronic, mechanical, and mechanical properties. According to the curled structure, single-walled carbon nanotubes can be classified into three types: armchair, serrated, and chiral (or helical); According to electronic structure, single-walled carbon nanotubes have semiconductor and metallic types (including quasi metallic and metallic types).

Electronic properties: Single walled carbon nanotubes have extremely high electron and hole mobility, which can increase the capacity of lithium batteries by 30% and be applied in logic circuits, solar cells, etc. ‌

Mechanical strength: The Young's modulus (elastic modulus) is about an order of magnitude higher than that of multi walled carbon nanotubes, which can significantly enhance material toughness. ‌

Other applications include sensors, scanning probe tips, catalyst carriers, and seawater desalination technology.
