The strong electrostatic interactions at the oil-water interface between a small molecule, 5,10,15,20-tetrakis(4-sulfonatophenyl)porphyrin, H6 TPPS, dissolved in water, and an amine terminated hydrophobic polymer dissolved in oil are shown to produce a supramolecular polymer surfactant (SPS) of H6 TPPS at the interface with a binding energy that is sufficiently strong to allow an intermolecular aggregation of the supramolecular polymers. SPSs at the oil-water interface are confirmed by in situ real-space atomic force microcopy imaging. The assemblies of these aggregates can jam at the interface, opening a novel route to kinetically trap the liquids in non-equilibrium shapes. The elastic film, comprised of SPSs, wrinkles upon compression, providing a strategy to stabilize liquids in non-equilibrium shapes.

使用界面超分子聚合来稳定液体。

结果表明，小分子5,10,15,20-四（4-磺酰基苯基）卟啉，H6 TPPS和溶于水的胺封端的疏水聚合物之间在油-水界面处具有很强的静电相互作用。在界面处产生H 6 TPPS的超分子聚合物表面活性剂（SPS），其结合能足够强以允许超分子聚合物的分子间聚集。油-水界面处的SPS通过原位实空间原子力显微成像确认。这些聚集体的组件可能会卡在界面上，从而开辟了一条新路线，以动力学方式将液体捕获为非平衡形状。由SPS组成的弹性膜在压缩时会起皱，从而提供了一种将液体稳定在非平衡形状中的策略。
