This invention discloses a method for preparing a copolymer ultrafiltration membrane. This method combines in-situ suspension polymerization, polyaddition reaction, sol-gel method, and non-solvent-induced phase separation to prepare a copolymer ultrafiltration membrane. Excellent hydrophilicity and component stability of the ultrafiltration membrane are achieved through stable covalent bonding between tannic acid and the copolymer. Furthermore, the in-situ polyaddition reaction and sol-gel reaction are combined to stably introduce high-performance tannic acid into the polymer membrane. Stable bonding of each component is achieved through co-hydrolysis and condensation polymerization of the copolymer and the siloxane on the modified tannic acid during the film formation process. The polymerization process of this invention is simple and the structure is tunable. The prepared material not only has excellent hydrophilicity and antifouling ability but also a stable structure, making it a cross-linked copolymer ultrafiltration membrane with antifouling and antibacterial adhesion properties.
