Graphene/polymer layered nanocomposites are studied extensively for their unique two‐dimensional (2D) layered nanoporous structures and interesting permeation properties with regard to ionic species, and show great potential for applications in many fields. Structural characterization is essential to the establishment of structure–properties relationships, which however remains challenging due to the complex, nanoporous texture rising from graphene alignment in graphene/polymer membrane materials. Here, a method is proposed that utilizes ions as probes for gaining structural information of the layered nanoporous structure. The results show that the subtle structural variations caused by the ..
