Summary: | Phys. Rev. E 106, 024502 (2022) Analytical relations for the mechanical response of single polymer chains are
valuable for modeling purposes, on both the molecular and the continuum scale.
These relations can be obtained using statistical thermodynamics and an
idealized single-chain model, such as the freely jointed chain model. To
include bond stretching, the rigid links in the freely jointed chain model can
be made extensible, but this almost always renders the model analytically
intractable. Here, an asymptotically correct statistical thermodynamic theory
is used to develop analytic approximations for the single-chain mechanical
response of this model. The accuracy of these approximations is demonstrated
using several link potential energy functions. This approach can be applied to
other single-chain models, and to molecular stretching in general. |
