Abstract
ABSTRACT The influence of the chain stiffness on the translocation of semiflexible polyelectrolyte through a nanopore is investigated using Langevin dynamics simulations. Results show that the translocation time τ increases with the bending modulus k θ because of the increase of viscous drag forces with k θ . We find that the relation between τ and k θ , the asymptotic behavior of τ on the polyelectrolyte length N , and the scaling relation between τ and the driving force f are dependent on k θ and N . Our simulation results show that the semiflexible polyelectrolyte chain can be regarded as either a flexible polyelectrolyte at small k θ or large N where its radius of gyration R G is larger than the persistence length L p or a stiff polyelectrolyte at large k θ or short N where R G < L p . Results also show that the out‐of‐equilibrium effect during the translocation becomes weak with increasing k θ . © 2019 Wiley Periodicals, Inc. J. Polym. Sci., Part B: Polym.
