Polyamide composite reverse osmosis membrane and preparation method thereof

Abstract

The present invention belongs to the technical field of membranes, and in particular relates to a polyamide composite reverse osmosis membrane and to a preparation method thereof. The polyamide composite reverse osmosis membrane provided by the present invention comprises: a nascent membrane and a temperature-responsive polypeptide grafted to a surface of the nascent membrane; the nascent membrane comprises a support layer and a polyamide separation layer joined to the support layer; the temperature-responsive polypeptide is a homopolymeric (L-glutamate) containing oligo(ethylene glycol). The polyamide composite reverse osmosis membrane provided in the present invention has excellent pollution resistance and oxidation resistance capabilities, has a low difficulty of cleaning, and has extremely broad market prospects.
