Latest Patents

Chunjun Ni's primary patent, titled "Efficient Antifouling and Hydrophilic Polyethersulfone Ultrafiltration Membrane and Preparation Method Thereof," presents a unique approach to creating a high-performance ultrafiltration membrane. The preparation method involves a Co-γ radiation grafting chemical modification technique that allows for the even distribution of an ionic liquid on the surface of polyethersulfone material. This inventive process enhances the adhesion of the ionic liquid, which contains unsaturated bonds, to the polyethersulfone through robust chemical bonding. The resultant asymmetrical porous membrane is processed using the immersion-precipitation phase transformation method and undergoes Soxhlet extraction, promoting the migration of grafted ionic liquid to the membrane's surface. As a result, Ni's ultrafiltration membrane exhibits superior antifouling properties, excellent pure water flux, and a high retention rate for bovine serum albumin (BSA).
