For example, we can observe that, between each time frame, in fiber (2) green monomers (defects) remain green ∼84% of the time, with a probability of ∼13.5% of transforming into purple (repaired defect) and ∼2.5% of exchanging and diffusing along the fiber. In fiber (3), the same probabilities are ∼71%, ∼27% and ∼1% percent. This comparison indicates that defects (green) are repaired faster in fiber (3) compared to fiber (2), and thus that they are less persistent. When looking at the orange monomers (absorbed, out-of-stack), in fiber (2) these have a surviving probability of ∼78%, while with a ∼21% probability these are reincorporated into the stack (transformed into green: reincorporated into a defect). In fiber (3) the situation is completely different. Orange monomers appear as a purely statistical short-lived state. In the rare cases where these are generated in fiber (3), coming from a defect (green) with a probability of ∼1%, these do not survive as orange absorbed monomers, but they are immediately reincorporated into the fiber stack (re-transformed into green monomers) with a probability as high as ∼93%. Thus, in fiber (3), monomer diffusion on the surface is substantially absent. In this sense, fiber (3) is a straight fiber that, from time to time, dynamically breaks forming intermittent defects that are continuously created and repaired, while, statistically, fiber (2) possesses a number of constitutional defects that are present along its length.
