Membrane technology has been drawn attention due to its energy-efficient, low cost, and its application. The viscoelastic properties of graphene oxide liquid crystals have the advantage of easy-controlling, so it let GOLC be coated on various geometries. GOLC has been hybridized with many different materials such as polymers, inorganic particles, and organic molecules. When high aspect ratios effectively integrated with impermeable fillers, the gas barrier performances are improved, which can be attributed to the increased diffusion length of tortuosity. The intercalation was determined by polymer’s characteristics like charges, functional groups and it affects the gas properties of the membrane. Herein, the investigation of intercalation between GO nanosheets with different types of polymers, which were ethylenediamine, polyacrylic acid, polyethyleneimine, polystyrene sulfonate, was conducted. Thus, the study showed the possible application for fabricating gas separation membrane.
