Abstract

Disclosed are a light-driven filtration antibacterial composite membrane and a preparation method and use thereof. The method for preparing the light-driven filtration antibacterial composite membrane includes: mixing dichloromethane and N,N-dimethylformamide to obtain a first solution; adding PCL particles to the first solution, and stirring until being uniform to obtain an electrospinning solution; adding a ZIF-8 powder to the electrospinning solution, and ultrasonically dispersing for at least 1 hour to obtain a PCL/ZIF-8 spinning solution; spraying the PCL/ZIF-8 spinning solution onto a PPCL@PDA/TAEG men-blown membrane to obtain the light-driven filtration antibacterial composite membrane.
