首次将甲基丙烯酸2-（全氟己基）乙酯（PEM）引入到苯乙烯包水高内相乳液（HIPE）模板的外相，合成了一系列乳液模板含氟聚合物（polyHIPE）。形态学（即，空隙尺寸及其分布）可以简单地通过改变PEM和/或表面活性剂的量来调节。表面化学和表面结构之间的协同效应使得聚HIPE具有疏水性，水接触角为151°。聚HIPE的超疏水性和亲油性，以及它们的高度开放的多孔结构，使得该材料在实践中作为用于油/水分离的过滤材料是非常有竞争力的候选物，其从油/水混合物中分离二氯甲烷的效率为95%。这种油/水分离能力在10次油/水过滤循环后保持不变，表明聚HIPE的循环使用是可行的。© 2018威利期刊股份有限公司J.

A series of emulsion‐templated fluorinated polymers (polyHIPEs) were first synthesized with introducing 2‐(perfluorohexyl)ethyl methacrylate (PEM) to the external phase of water‐in‐styrene high internal phase emulsion (HIPE) templates. The morphology (i.e., void size and its distribution) of these porous materials could be tuned simply by changing PEM and/or surfactant amount. The synergistic effect between the surface chemistry and surface architecture allowed the polyHIPEs to possess hydrophobicity with a water contact angle of 151°. The superhydrophobicity and oleophilicity of the polyHIPEs, together with their highly open porous structure, make the material a very competitive candidate as a filtration material for oil/water separation in practice with the efficiency of separating dichloromethane from the oil/water mixture of 95%. Such oil/water separating capacity was maintained after 10 cycles of filtration of oil/water, indicating the cyclic usage of the polyHIPE is feasible. © 2018 Wiley Periodicals, Inc. J. Polym.
