Supplementary Figure 10: Contractive measurements.
From: Preparation of biomimetic hierarchically helical fiber actuators from carbon nanotubes
(a) Experimental setup for the contractive measurement. Scale bar, 10 cm. (b) Clamping the two ends of the fibre on the table-top universal testing instrument. Scale bar, 1 cm. (c) Cutting the two shoulders of the paper (the area marked in dashed line in b), followed by touching with the solvent. Scale bar, 1 cm.
