Is there a fundamental theory of polymer fibers and nanofibers?
I work with polymer fibers and I am interested in whether there is a fundamental theory to describe them. Suppose fibers are composed of an amorphous rather than crystalline polymer. If they are very thin, they will be unstable for two reasons. Firstly, they have a large free surface area and hence high surface energy. Secondly they are usually composed of highly oriented polymer molecules, which are entropy depleted and tend to adopt a Gaussian coil conformation. Despite the effect of these two factors, nanofibers made of amorphous polymers can be stable in some cases.
Are there theories that estimate the limits of their stability (taking into account the flexibility of polymers and the interaction energy between links)? Are such theories applicable to partially crystalline polymers? I am 100% sure that these theories exist, could you please help me to find them?
There are several fundamental theories and methods for understanding the stability of polymer fibers and nanofibers, particularly those made from amorphous polymers. Key theories include the Gibbs-Thomson effect, which addresses the impact of surface energy on fiber stability, and the Flory-Huggins theory, which examines polymer interactions and thermodynamics. These frameworks can also be adapted to partially crystalline polymers by considering the contributions of crystalline regions to overall material properties.
Dear Dmitry Bagrov, please have a look at the following book and the attached file. My Regards

Dmitry Bagrov are u still working with polymeric fibers? If our interests match, we can work together and form a collaboration?
