摘要： A semipermeable composite membrane that reduces an environmental load, and a method of producing the semipermeable composite membrane. A semipermeable composite membrane includes, on a porous support, a semipermeable membrane containing a crosslinked polyamide and a cellulose nanofiber. A method of producing the semipermeable composite membrane includes obtaining a mixed solution containing the cellulose nanofiber, water, and an amine component, and obtaining the semipermeable composite membrane by making the mixed solution be in contact with the porous support, thereafter, causing a cross-linking reaction of the amine component in the mixed solution, with the amine component adhering to the porous support.

摘要： The invention provides a semipermeable composite membrane that reduces an environmental load, and a method of producing the semipermeable composite membrane. A semipermeable composite membrane 100 includes, on a porous support 102, a semipermeable membrane 104 containing a crosslinked polyamide 120 and a cellulose nanofiber 110. A method of producing the semipermeable composite membrane includes obtaining a mixed solution containing the cellulose nanofiber 110, water, and an amine component, and obtaining the semipermeable composite membrane 100 by making the mixed solution be in contact with the porous support 102, thereafter, causing a cross-linking reaction of the amine component in the mixed solution, with the amine component adhering to the porous support 102.
