摘要
石墨烯作为一种具有单原子层厚度的二维纳米片,凭借石墨烯基独特的物理性质,已成为高性能碳捕集膜的构筑单元。石墨烯基纳米片超薄的厚度有助于制备超薄膜以提升分离膜的通量,此外可调的物理化学性质赋予石墨烯二维通道内多样的微环境。以CO2分离膜内多重传质机理为出发点,重点介绍近年来石墨烯基CO2分离膜二维通道物理化学微环境精密调控的策略及进展,期望对石墨烯基CO2分离膜的理性设计和可控制备提供清晰思路。
Graphene,as a two-dimensional nanosheet with the thickness of monoatomic layer,has become a unit of high-performance carbon capture membranes due to its unique physical property.The ultrathin thickness of graphene-based membranes is conducive to the preparation of ultrathin membranes in order to improve the flux of separation membranes.Upon that,the adjustable physicochemical property endows multiple microenvironment within the two-dimensional channel of graphene.In view of the multiple mass transfer mechaisms of CO2 separation membranes,it highlights the strategies and progress of precision controllable of physiochemical microenviroment within the two-dimensional channel of graphene in recent years.Expecting to provide a clear thinking for the reasonable design and controllable equipment of graphene-based CO2 separation membranes.
