WebThe diameters of MWNT are typically in the range of 5 nm to 50 nm. The interlayer distance in MWNT is close to the distance between graphene layers in graphite. MWNT are easier to produce in high volume quantities than SWNT. However, the structure of MWNT is less well understood because of its greater complexity and variety. Webbetween SWNT and MWNT arises from number of concentrically rolled up graphene sheets. For SWNTs, only one rolled up graphene sheet is there whereas for two or more concentrically rolled up graphene sheets, CNTs are known as MWNT. SWNT bundle is formed by packing together a large number of SWNTs in a bundle form.
