The invention discloses an
electricity-assisted slow-release antibacterial conductive
ultrafiltration membrane and a preparation method and application thereof, and belongs to the technical field of
sewage treatment, the
electricity-assisted slow-release antibacterial conductive
ultrafiltration membrane comprises a matrix, an antibacterial filler and a conductive filler, the matrix is polyether
sulfone, the antibacterial filler is hollow
mesoporous carbon spheres loaded with broad-spectrum bactericide povidone
iodine, and the conductive filler is an aminated
carbon nanotube; the preparation method comprises the following steps: S1, synthesizing hollow
mesoporous carbon spheres by adopting a template method; s2, immersing the hollow
mesoporous carbon spheres into a
povidone iodine solution for adsorption to obtain hollow
nano carbon spheres loaded with an
antibacterial agent; s3, adopting an impregnation
phase conversion technology, and adding antibacterial filler-povidone
iodine loaded hollow mesoporous carbon spheres and conductive filler-aminated carbon nanotubes into the membrane
casting solution to successfully construct the slow-release antibacterial composite conductive
ultrafiltration membrane. The antibacterial slow-release nano material and the conductive nano material are organically combined with the ultrafiltration membrane, so that the screening performance and the anti-
pollution performance of the ultrafiltration membrane are improved, and the
biological pollution of the membrane and the loss of an
antibacterial agent are reduced.
