Figure 3

(a) A schematic of nanotube tensile testing set-up and an optical microscopic image of the MWCNT mounted on the frame (1 mm in length and 98 μm in diameter). (b) The stress-strain curves of the millimeter-long vertical aligned MWCNTs. (The length and diameter of specimens are in ranges from 0.75 to 2.15 mm, and 25 to 107 μm, respectively.)
