在本文中，我们使用模拟和理论来了解柔性和半柔性系链聚合物在高剪切流限制下的情况，从而导致链接近完全延伸。我们采用沿着聚合物轴的随机游走图，结合沿着链轮廓的扰动的统计机械描述，使我们能够在没有任何拟合参数的情况下充分表征聚合物链的几何形状。还研究了流体动力相互作用的结合，流体动力升力引起系链点附近链平衡结构的变化，这可能对吸附和解吸动力学产生影响。
In the present article, we use simulation and theory to understand the case of flexible and semiflexible tethered polymers in the limit of high shear flows and consequently near-full extension of the chains. We adopt a random-walk picture along the axis of the polymer, which in combination with a statistical mechanical description of perturbations along the chain contour allows us to fully characterize the geometry of the polymer chain without any fit parameters. Incorporation of hydrodynamic interactions is also investigated, with the hydrodynamic lift force inducing changes in the chain equilibrium structure near the tether point that could have implications for adsorption and desorption kinetics.
