Typical characteristics of SNCNTs and MWCNTs.

Table 1: Typical characteristics of SNCNTs and MWCNTs.

Outside diameter

(nm)

Core diameter

(nm)

Specific surface area

(m²/g)

SWCNTs

0.4-3.0

E.g.: 550^* (751^a ; 484^b)^**

MWCNTs

< 100

> 2.0

E.g.: 280^* (40 to 600) [14]

*SWCNT and MWCNT purchased from Research Institute of Petroleum Industry of Iran [12].
**Theoretical calculation: a) Small bundle of 7 aligned SWCNT; b) Bundle made up of 19 aligned SWCNTs [11].
