论文摘要
覆盖水合物是一种天然存在的冰状固体，在一个或多个疏水分子的情况下，在适当的温度和压力条件下以水相形成。它还在油气管道内形成，导致抽水成本更高，流动阻塞甚至灾难性事故。具有低水分粘附的工程表面可以为此问题提供有效的解决方案。液体浸渍表面是工程表面的一个例子，它在减少固体的成核和粘附方面已经显示出巨大的潜力。在这里，我们报告了在油和水的混合环境下，液体浸渍表面的设计和合成。设计这些表面最具挑战性的方面是同时在水和油下同时稳定润滑剂层。描述并通过实验验证了一种从理论角度来使这种润滑剂稳定表面的详细方法，以实现润滑剂稳定性。在此类表面上的实验测量表明，水合物的积累极低，水合粘附力的一个数量级或更多的降低。
Clathrate hydrate is a naturally occurring ice-like solid which forms in water phase under suitable temperature and pressure conditions, in the presence of one or more hydrophobic molecules. It also forms inside the oil and gas pipes leading to higher pumping cost, flow blockage and even catastrophic accidents. Engineered surfaces with low hydrate adhesion can provide an effective solution to this problem. Liquid impregnated surfaces is one such example of engineered surfaces which has already shown tremendous potential in reducing the nucleation and adhesion of solids. Here we report the design and synthesis of liquid impregnated surfaces with extremely low hydrate adhesion under the mixed environment of oil and water. The most challenging aspect of designing these surfaces was to stabilize a lubricant layer simultaneously under the water and oil. A detailed methodology to make such lubricant stable surfaces from theoretical perspective was described and experimentally validated for lubricant stability. Experimental measurements on such surfaces showed extremely low hydrate accumulation and one order of magnitude or more reduction in hydrate adhesion force.
