The carbon nanotubes market is segmented by type, technology, application, end user and geography
Based on type, the carbon nanotubes market is segmented into Single-Walled Carbon Nanotubes (SWCNT) and Multi-Walled Carbon Nanotubes (MWCNT). Among these, the MWCNT segment dominated the carbon nanotubes market in 2018. Due to the unique performance characteristics. For instance, multi-walled carbon nanotubes withstand extreme temperatures as they have atomic bonds which are highly strong. Additionally compared to copper wires this has good thermal conductor’s properties which can transmit around 15 times the amount of watt.
On the basis of technology, the carbon nanotubes market is segmented into chemical vapor deposition (CVD), catalytic chemical vapor deposition (CCVD) and high pressure carbon monoxide reaction (HIPCO). The CVD segment accounted for the largest share in the carbon nanotubes market in 2018, owing to the cheapest among all, with the increased production and improving technologies, prices for CVD are expected to decrease incrementally.
Based on application, the carbon nanotubes market is segmented into structural polymer composites, conductive polymer composites, conductive adhesives, fire-retardant plastics, metal matrix composites and li-ion battery electrodes. The polymer composites have been found to have excellent friction and wear performance after being modified with functional fillers and reinforcements. This advantage makes them flexible in many industrial applications.
By end user the market is segmented into electrical & electronics, aerospace & defense, energy, sporting goods, automotive and industrial. The Aerospace & Defense segment dominated the carbon nanotubes market in 2018, due to their capability to facilitate designing of lightweight parts.
