In the search for selective, productive and robust membranes for gas and other separations, highly permeable polymers, such as the prototypical polymer of intrinsic microporosity PIM-1, have been combined with a wide range of polymers, metal-organic frameworks, 2D materials and other fillers. Recent research has highlighted the importance of optimising the polymer used for the continuous phase, as well as achieving good compatibility between the different components. Many studies have focused on relatively thick films (>20 μm) and more work is needed to understand and control the behaviour of thin films (typically <1 μm) that are more relevant to real-life applications.

在寻找用于气体和其他分离的选择性、高效和坚固的膜时，高渗透性聚合物，例如固有微孔 PIM-1 的原型聚合物，已与多种聚合物、金属有机框架、二维材料和其他填充物。最近的研究强调了优化用于连续相的聚合物以及实现不同组分之间良好相容性的重要性。许多研究都集中在相对较厚的薄膜（> 20 μm）上，需要做更多的工作来理解和控制与实际应用更相关的薄膜（通常<1 μm）的行为。
