where P0 is considered the temperature-independent persistence length.
For the shortest fibers, the average persistence length is 203 ± 70 nm, which is within error of the persistence length of the longest fibers.
This is believed to be due to the enhanced chain flexibility, and hence reduced persistence length.
Variations of the persistence length and mean chain dimensions with bending stiffness are presented.
This evolution is discussed in terms of an increase of the electrostatic persistence length.
The program calculates persistence length from microscopy images of DNA according to Frontali et al.[33].[33]
In two images, a persistence length (about 600 nm) was obtained.
The persistence length of the UHMM hyaluronan polymer has been estimated.
Chain stiffness is characterised in terms of the persistence length, which is close to 50 nm.
However, quantitative data on the persistence length of IFs are still missing.
For example, a typical flexible copolymer, polystyrene, exhibits a persistence length of 0.9 nm [10] and a rigid copolymer, polyphenylene with sulfonate ester side groups exhibits a persistence length of 13 nm [14, 43].
