含─C(CF3)2─共聚酰亚胺前驱体热解制备 CMS 膜，超微孔收紧实现丙烯/丙烷分离
Ultramicropore Tightening in Carbon Molecular Sieve Membranes Enables Entropy‐Dominated Propylene/Propane Separation
AI 导读
研究以含可调浓度─C(CF3)2─大体积单元的氟化共聚酰亚胺为前驱体，通过组成与热解温度调控实现碳分子筛（CMS）膜超微孔收紧并保留可及微孔传输通道。
推荐理由
原文给出含─C(CF3)2─共聚酰亚胺前驱体组成与热解温度对 CMS 超微孔收紧的调控关系，以及混合气分离数据。
创新点
通过调节氟化共聚酰亚胺前驱体中─C(CF3)2─单元浓度提高前驱体自由体积并增强热解挥发，从而在保留可及微孔传输的同时收紧超微孔，把分离选择性来源指向构型熵限制而非单纯尺寸筛分。
