摘要: A high-flux composite nanofiltration (NF) membrane with an electrical double layer (EDL) and a preparation method thereof are provided. The high-flux composite NF membrane includes: a charged support membrane and a charged separation layer, where a charge carried by the support membrane or the separation layer is a positive charge, a negative charge, or an amphiprotic charge. The high-flux composite NF membrane with an EDL solves the technical problem that the composite NF membrane in the prior art has an unsatisfactory retention rate and a limited application range due to a small charge quantity.
