Empirical Correlation of the Morphology of Coiled Carbon Nanotubes with Their Response to Axial Compression

Figure 3

Force curve data collected during compression of the CCNT at an approach angle of 7° to the surface. The total z-piezo scanner size was held constant at 2500 nm. The compression amounts on the nanocoil were increased by changing the start position of the scanner cycle. The force curves are collected at (a) 125, (b) 250, (c) 375, (d) 500, (e) 750, and (f) 875 nm of compression distance. The data are offset so that the jump to contact in the approach curves (blue) is aligned for comparison. Magenta traces denote retract curves.
