Novel biological pollution-resistant polyamide reverse osmosis composite membrane and preparation method thereof

The invention discloses a novel biological pollution-resistant polyamide reverse osmosis composite membrane and a preparation method thereof. The preparation method comprises carrying out graft modification on a polyamide reverse osmosis membrane through atom transfer radical polymerization (ATRP), carrying out sterilization particle loading to obtain a reverse osmosis composite membrane with bioattachment resistance and antibacterial properties. The reverse osmosis composite membrane polymerization process is carried out at the room temperature and has high controllability. The reverse osmosis composite membrane can be conveniently and fast prepared, has stable performances, effectively improves use efficiency and a use life and reduces a seawater desalination cost.
