Features of single wall carbon nanotube:
Single-walled carbon nanotubes (SWCNT or SWNT) are all composed of carbon atoms. The geometric structure can be regarded as single-layer graphene curled. The structure determines the properties. Therefore, single-walled carbon nanotubes have excellent electronics, machinery, mechanics, etc. performance. Simultaneously, according to the curl structure, single-walled carbon nanotubes have three types: armchair, zigzag, and chirality; according to electronic structure, single-walled carbon nanotubes have semiconductor type and metal type (including metalloid and metallic).
Application:
The high-cost performance of single-walled carbon nanotubes makes them a new generation of conductive additives in various industries. It can be used as a general additive to improve the performance of most materials, including polymer composites, rubber, metals, and others.
