Adsorption-active polydisperse brush with tunable molecular mass distribution
Anna S. Ivanova, Alexey A. Polotsky, Alexander M. Skvortsov +2
Recently a novel class of responsive uncharged polymer brushes has been proposed [Klushin et al, J. Chem. Phys. 154, 074904 (2021)] where the brush-forming chains have an affinity…
Polymer brushes with reversibly tunable grafting density
Leonid I. Klushin, Alexander M. Skvortsov, Alexey A. Polotsky +2
We propose a novel class of responsive polymer brushes, where the effective grafting density can be controlled by external stimuli. This is achieved by using end-grafted polymer ch…
Anomalous Critical Slowdown at a First Order Phase Transition in Single Polymer Chains
Shuangshuang Zhang, Shuanhu Qi, Leonid I. Klushin +3
Using Brownian Dynamics, we study the dynamical behavior of a polymer grafted onto an adhesive surface close to the mechanically induced adsorption-stretching transition. Even thou…
Phase transitions in single macromolecules: loop-stretch transition versus loop adsorption transition in end-grafted polymer chains
Shuangshuang Zhang, Shuanhu Qi, Leonid I. Klushin +3
We use Brownian dynamics simulations and analytical theory to compare two prominent types of single molecule transitions. One is the adsorption transition of a loop (a chain with t…
Polydisperse polymer brushes: internal structure, critical behavior, and interaction with flow
Shuanhu Qi, Leonid I. Klushin, Alexander M. Skvortsov +1
We study the effect of polydispersity on the structure of polymer brushes by analytical theory, a numerical self-consistent field approach, and Monte Carlo simulations. The polydis…
Stimuli-responsive brushes with active minority components: Monte Carlo study and analytical theory
Shuanhu Qi, Leonid I. Klushin, Alexander M. Skvortsov +2
Using a combination of analytical theory, Monte Carlo simulations, and three dimensional self-consistent field calculations, we study the equilibrium properties and the switching b…
Sharp and fast: Sensors and switches based on polymer brushes with adsorption-active minority chains
Leonid I. Klushin, Alexander M. Skvortsov, Alexey A. Polotsky +2
We propose a design for polymer-based sensors and switches with sharp switching transition and fast response time. The switching mechanism involves a radical change in the conforma…
Escape transition of a polymer chain from a nanotube: how to avoid spurious results by use of the force-biased pruned-enriched Rosenbluth algorithm
Hsiao-Ping Hsu, Kurt Binder, Leonid I. Klushin +1
A polymer chain containing monomers confined in a finite cylindrical tube of diameter grafted at a distance from the open end of the tube may undergo a rather abrupt tr…
Dragging a polymer chain into a nanotube and subsequent release
Leonid I. Klushin, Alexander M. Skvortsov, Hsiao-Ping Hsu +1
We present a scaling theory and Monte Carlo (MC) simulation results for a flexible polymer chain slowly dragged by one end into a nanotube. We also describe the situation when the…
