Figure 2: Model of the node-guided contacting mode.

From: Carbon nanotube dry adhesives with temperature-enhanced adhesion over a large temperature range

Figure 2

(a,b) SEM images for the CNT adhesive after detachment, showing web-like CNT segments on the top of the CNT adhesive (a) and the copper surface (b), respectively, after testing at 1,033 °C (scale bar, 1 μm). (c) A higher magnification view of the CNT web selected by the dotted box in a (scale bar, 0.5 μm). (d) nonaligned top CNT segments of the pristine vertically aligned double-walled CNT (VA-DWNT) array under the same magnification as b for comparison (scale bar, 1 μm). (eg) SEM images of the CNT bundle deformation under normal preloading to induce line contacts with the target surface through the web-like deformation (scale bar: (e) 20 μm; (f) 20 μm; (g) 1 μm). The individual CNT bundle was drawn and twisted by a pair of tweezers from the CNT dry adhesive to mimic the plasma-induced bundles with top nodes. Due to technical difficulties, the actual size of the individual CNT bundle thus produced is at least 20 times that of the plasma-induced bundles. (hj) The corresponding schematic depictions for eg.
