Figure 5.

Fn fibers exhibited permanent deformation after fiber creep testing. A single Fn fiber (initial length 107 μm) was stretched 3 times for 30 min at a constant force of 960 nN, shown in the subplot, and was allowed to relax for 15 min between tests. Stretch 1 is shown in blue, stretch 2 is shown in red, and stretch 3 is shown in green. Permanent deformation was observed as lengthening of the fiber after each creep test.
