Abstract:

With the wide application of polymer membrane materials in the fields of water treatment technology,medicine,food,agriculture and chemical industry,it has become a hot topic in recent years to improve the bacteriostasis,anti-pollution and water flux of polymer membrane materials by different methods in order to prolong the service life of polymer membrane materials.The main applications of silver-containing polymer membrane materials were introduced.The different effects of silver and silver ions on the modification of polymer membrane materials were described respectively.The modification methods of silver-containing polymer membrane materials by phase transformation,blending,in-situ synthesis,ion exchange and interfacial polymerization were discussed.The optimization of antibacterial performance,anti pollution performance and water flux of polymer membrane materials modified by different modification methods were summarized.The addition of silver could improve the bacteriostatic rate of polymer membrane materials,and the bacteriostatic rate could reach 100%.The addition of silver could effectively improve the anti-pollution performance of membrane materials,and its water flux to polymer membrane materials was also improved to a certain extent.

Key words: silver, polymer membrane material, modification, bacteriostasis, anti-pollution
