后退接触线上图形沉积形成的动力学模型
Dynamical model for the formation of patterned deposits at receding contact lines
摘要：
我们描述了在许多不同的实验中观察到的沉积图案的形成，其中挥发性纳米颗粒悬浮液或聚合物溶液的三相接触线后退。基于长波近似的动力学模型预测沉积的不规则和规则的线图案，由于自组织的钉扎-脱钉循环对应于粘滑运动的接触线。我们分析了蒸发速率和溶质浓度对谱线性质的影响。
英文摘要：
We describe the formation of deposition patterns that are observed in many different experiments where a three-phase contact line of a volatile nanoparticle suspension or polymer solution recedes. A dynamical model based on a long-wave approximation predicts the deposition of irregular and regular line patterns due to self-organised pinning-depinning cycles corresponding to a stick-slip motion of the contact line. We analyze how the line pattern properties depend on the evaporation rate and solute concentration.
