Multi-walled carbon nanotubes or MWCNT, are unique forms of incredibly thin materials with unbelievable strength, electrical, and heat properties. They consist of several walls of graphene with a tubular shape. MWCNT are applied in an increasing number of industries nowadays.
Understanding Multi-Walled Carbon Nanotubes
Multi-walled carbon nanotubes consist of multiple layers of graphene stacked on top of each other, like tubes within tubes. Their outer and inner walls account for their vast strength, electrical conductivity, and thermal resistance. MWCNT are stronger and easier to synthesize compared to single-walled carbon nanotubes (SWCNT) and are therefore more suitable for application in industries.
