This technology describes a composite gas separation membrane for hydrogen separation, comprising an anodic aluminum oxide layer, a carbon nanotube layer, and a polymer material that fills their pores, as well as its manufacturing method.
Conventional nano-membrane gas separation membranes have issues with low strength, difficult handling, and poor durability.
This technology fills a multi-layered porous structure with a polymer, providing high hydrogen selectivity along with excellent mechanical strength and durability, making it suitable for impurity gas filtration in hydrogen production processes.
