We report surface rheological measurements on Langmuir films of submicron-sized polymer coils (pancakes). The dynamics of the sol phase is found to be governed by free volume as in the simplest percolation problem. The observed rheology of the percolated phase (gel-like) is compatible with predictions for compressed arrangements of highly deformed soft particles interacting through their contact interfaces.
我们报告了对亚微米尺寸聚合物线圈（薄饼状）的朗缪尔膜进行的表面流变学测量。结果发现，溶胶相的动力学如同在最简单的渗流问题中一样，受自由体积支配。所观察到的渗流相（类凝胶状）的流变学与通过接触界面相互作用的高度变形软颗粒的压缩排列预测相符。
