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…
Defect-free Perpendicular Diblock Copolymer Films: The Synergistic Effect of Surface Topography and Chemistry
Xingkun Man, Pan Zhou, Jiuzhou Tang +2
We propose a direct self-assembly mechanism towards obtaining defect-free perpendicular lamellar phases of diblock copolymer (BCP) thin films. In our numerical study, a thin BCP fi…
Lamellar Diblock Copolymers on Rough Substrates: Self-consistent Field Theory Studies
Xingkun Man, Jiuzhou Tang, Pan Zhou +2
We present numerical calculations of lamellar phases of di-block copolymers (BCP) confined between two surfaces, where the top surface is flat and the bottom one is corrugated. The…
Volume Phase Transition of Polyelectrolyte Gels: Effects of Ionic Size
Li-Jian Qu, Xinghua Zhang, Jiuzhou Tang +1
Although the volume transition of the polyelectrolyte gel has been studied for decades, little research on the effects of size of the mobile ions has been conducted. In the present…
Poisson-Nernst-Planck Model of Bipolar Nano uidic Diode Based on Bulletlike Nanopore
Li-Jian Qu, Xinghua Zhang, Jie Fua +2
Bipolar nanofluidic diode is based on nanopore with positive and negative surface charges separated by a junction. This paper investigates the effects of the pore structure, taking…
