  • Publication number: 20240399313
    Abstract: Provided is a method for preparing a durable hydrophilic ultrafiltration membrane. In the disclosure, a functional hydrophilic molecule is synchronously synthesized during conventional dissolution of a polymer membrane material; and a resulting casting solution (a nascent membrane) is introduced into a coagulation bath, which initiates a cross-linking reaction between the functional hydrophilic molecules to form a hydrophilic cross-linked network. A hydrophilic cross-linked interpenetrating network is formed in situ during polymer phase separation to limit movement of polymer chains and formation and growth of micelles, thereby forming a relatively uniform polymer interpenetrating network structure to obtain the durable hydrophilic ultrafiltration membrane with a relatively uniform membrane pore structure.

  • Patent number: 11623183
    Abstract: The present disclosure provides the synthesis of an imidazolium-based functional ionic liquid copolymer (PMMA-b-PIL-R*) and a preparation method of an alloy ultra-filtration membrane. Firstly, PMMA-b-PIL-R* is prepared from methyl methacrylate (MMA) and polymerizable imidazolium-based functional ionic liquid (IL-R*) containing double bonding as the reactive monomers through sequential radical polymerization. With the use of a non-solvent induced phase separation method, PMMA-b-PIL-R* is introduced into the body of a polymeric membrane material, so as to prepare an alloy ultra-filtration membrane. A hydrogen-bond interaction is generated between the carbonyl in the molecular chain of PMMA-b-PIL-R* and the H . . .

  • Publication number: 20230035042
    Abstract: A method for preparing a durably hydrophilic and uniform-pore ultrafiltration membrane is disclosed herein. Chemical reactions between the functional groups and the active bonds of the molecular chains in the membrane materials are initiated perform the grafting of hydrophilic chains on the polymer chains under conventional dissolution conditions of the polymer membrane material (dissolution with synchronized hydrophilization), so as to realize durable hydrophilization of the membrane materials. The resulting hydrophilized polymer solution (a nascent-state membrane) is introduced into a coagulation bath to initiate a crosslinking reaction among the hydrophilic chains. The resulting crosslinking serves to synergistically regulate subsequent phase separation and membrane formation (phase separation under synergistic crosslinking).
