  具有固有微孔性的高选择性螺二芴基聚合物的合成，链堆积模拟和长期气体渗透性†

  摘要：

  由内在微孔性聚合物（SBF-PIMs）组成的膜具有用于工业气体分离的潜力。在这里，我们报告了一个组合的模拟和实验研究，以通过将简单的取代基（例如甲基，叔丁基和稠合的苯并）放置在衍生自螺二芴（PIM-SBFs）的PIM上来研究对聚合物微孔率和气体渗透性的影响。已显示甲基或叔丁基取代基均引起气体渗透率的大幅增加，其中四个甲基增强了超微孔的浓度（<0.7 nm），这有助于选择性的气体传输。该Ť丁基取代基会产生较大浓度的较大，选择性较低的微孔（> 1.0 nm），从而降低选择性。长期老化研究（> 3.5年）证明了PIM-SBFs作为用于气体分离的高性能膜材料的潜力。尤其是，源自四甲基取代的SBF的PIM数据达到了拟议的2015年Robeson上限O 2 / N 2，因此对于空气中氧气或氮气的富集具有希望。老化的PIM-SBF的CO 2 / CH 4的混合气体渗透率测量结果也显示出其天然气或沼气升级的潜力。

• A Spirobifluorene-Based Polymer of Intrinsic Microporosity with Improved Performance for Gas Separation

  日期：2012.11.20

  A highly gas‐permeable polymer with enhanced selectivities is prepared using spirobifluorene as the main structural unit. The greater rigidity of this polymer of intrinsic microporosity (PIM‐SBF) facilitates gas permeability data that lie above the 2008 Robeson upper bound, which is the universal performance indicator for polymer gas separation membranes.

  使用螺二芴作为主要结构单元，可以制备出具有更高选择性的高透气性聚合物。这种具有固有微孔性（PIM-SBF）的聚合物具有更高的刚性，有助于获得高于2008 Robeson上限的气体渗透率数据，该数据是聚合物气体分离膜的通用性能指标。
