Abstract The disposal of waste masks has become a new challenge due to the spread of COVID-19. In this work, the superhydrophilic membrane with excellent oil/water separation performance was prepared by in situ deposition of SiO₂ nanoparticles and grafting dopamine (DA) on the surface of waste masks. The modified waste-mask membrane exhibits good properties with water contact angle of 0°, the water flux of 6 953 L·m^-2·h^-1 under gravity and the oil/water separation efficiency of 98.65%. The modified membrane maintains a good stable performance in acidic and alkaline solutions (pH=2—14). This work provides a new and economic way for the disposal and recycle of waste masks.
