摘      要：Carbon molecular sieve membranes(CMSMs)are a class of porous membranes inherited with excellent thermal stability,high tolerance and superior mechanical *** to their nanoporous structures,CMSMs usually hold significant potential for gas separation ***,hyper-crosslinked ionic polymer(HIP)membranes possess a highly crosslinked nitrogen-rich framework,high thermal stability together with exceptional mechanical strength,making them excellent precursors for the CMSMs *** pyrolysis of HIP membranes,the resulting CMSMs featured with nitrogen functional sites exhibit strong interactions with CO_(2),which significantly reduces the CO_(2)permeability while other gas molecules continue to flow through the nanoporous *** resultant CMSMs exhibited excellent H_(2)/CO_(2)selectivity with values of 10.75 and 7.09,together with ultra-high H_(2)permeability of 3052 and 9181 barrer,respectively,surpassing the Robeson upper *** preparation route towards CMSMs with high nitrogen content from HIP can significantly enrich the rational design and synthesis strategies of high-performance gas separation CMSM materials.
