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： Disclosed is a method for the production of a porous polymer membrane suitable for liquid filtration or analyte capture, comprising the steps of: providing a flowable composition (100) on a substrate (220) the composition including at least: photo-activatable monomer molecules, photo activation initiator molecules and photo-activation quencher molecules; providing one or more pulses (L) of laser light at at least one focal point in the composition of sufficient energy to locally polymerise the composition; moving the or each focal point relative to the previously polymerised composition in a continuous or stepwise predetermined manner to a multiplicity of further positions; and repeating the pulse(s) at those further positions such that a three dimensional matrix of the composition is polymerised leaving unpolymerized areas of a size equivalent to conventional polymer membrane pores.

摘要： The present disclosure relates to a polyether block polyamide/polydimethylsiloxane (PDMS) composite membrane for gas separation, and a preparation method and use thereof, and belongs to the technical field of membrane separation. In the present disclosure, an amphoteric copolymer PDMS-polyethylene oxide (PEO) (PDMS-b-PEO) is introduced into an intermediate layer to adjust the interfacial binding performance, thereby promoting preparation of an ultra-thin polyether block polyamide composite membrane. Studies have shown that the surface enrichment of PEO segments not only inhibits a dense SiOx layer formed due to a plasma treatment of a PDMS intermediate layer, but also provides additional hydrophilic sites and interfacial compatibility for the subsequent selective layer. The use of PDMS-b-PEO in an intermediate layer allows the successful preparation of a selective layer with a thickness of about 50 nm.
