Abstract:Polyimide fiber is a typical synthetic material， the molecular chain consists of alternating benzene rings and imide rings. Due to the low rotational energy， the molecular chain exhibits relative rigidity， endowing the material with high strength， high modulus， high temperature resistance， radiation resistance， chemical resistance， and excellent flame retardant. These properties make it has a good potential for application in the field of high-temperature gas filtration and separation. This paper reviewed the preparation technology of paper-based materials， membrane materials， and foam materials based on polyimide fibers， discussed the latest research progress of polyimide fiber-based gas filtration and separation materials， and looked forward to the future of the series of polyimide-based gas filtration and separation materials.
