Latest Patents

Kazuo Hasumi holds a patent for a process aimed at producing membranes for use in gas separation. The patent describes a method for creating a gas separation membrane that includes a microporous support with a non-porous coating layer. This method involves melt extruding a thermoplastic crystalline polymer under specific conditions to form a precursor, which can be either a hollow fiber or a flat film. The precursor is then coated with a substance that forms a polymeric layer, ensuring that no pinholes develop during the subsequent drawing process. The support undergoes annealing, followed by cold drawing and heat setting to finalize the gas separation membrane. This innovative approach enhances the efficiency and effectiveness of gas separation processes.
