Nanowire reverse osmosis composite membrane and preparation method thereof

The invention discloses a nanowire reverse osmosis composite membrane and a preparation method thereof. The nanowire reverse osmosis composite membrane comprises: a supporting layer, a polyamide functional layer and a nanowire antibacterial layer; wherein the polyamide functional layer is arranged on the supporting layer, nanowires are self-assembled on the surface of the polyamide functional layer through physical or chemical action to form the nanowire antibacterial layer; particularly, the preparation method comprises steps of: uniformly pouring the nanowire solution on the surface of the polyamide reverse osmosis membrane, performing standing treatment for a period of time, pouring out the redundant nanowire aqueous solution, and fully rinsing the surface of the membrane by using deionized water. By means of the membrane, leakage of the loading material under the action of strong water flow is avoided, the loading capacity of the nano material on the surface of the membrane is ensured, and the advantage o
