Abstract: The present disclosure relates to a conjugated polyelectrolyte-grafted membrane, which is obtained by fixing a conjugated polyelectrolyte (CPE) capable of generating active oxygen under visible light irradiation to a membrane through crosslinking, and can remove contaminants in water, while reducing bio-fouling on the surface of the membrane, by generating active oxygen through a photocatalytic reaction of the conjugated polyelectrolyte (CPE), as well as to a method for manufacturing the same. The method for manufacturing a conjugated polyelectrolyte-grafted membrane includes the steps of: preparing a conjugated polyelectrolyte (CPE); coating a conjugated polyelectrolyte (CPE) on the surface of a membrane; and carrying out crosslinking of the conjugated polyelectrolyte (CPE) with the surface of the membrane.
