^{Product Overview}

Carbon nanotubes, also known as buckytubes, can be viewed as seamless hollow circular tubes formed by winding a single layer of graphite hexagonal grid plane along chiral vectors, with carbon atoms typically capped at both ends in pentagons. Therefore, the carbon atoms in carbon nanotubes are mainly sp2 hybridized, and once the hexagonal network structure forms a spatial topology, a certain sp3 hybridization can be formed. The diameter of SWCNT is generally between 1-2 nm. Single walled carbon nanotubes can reach lengths of micrometers, even millimeters and centimeters, with a large aspect ratio and superior electrical, mechanical, and thermal properties.
