Abstract: The present disclosure relates to a porous polymer actuator which maintains the porous structure of the polymer actuator by forming a conductive polymer layer on a commercially available porous polymer separation membrane by vapor-phase polymerization and is capable of improving fast responsiveness to organic solvents and durability by ensuring structural anisotropy, and a method for fabricating the same. The porous polymer actuator according to the present disclosure includes: a porous polymer separation membrane having pores; and a conductive polymer layer coated on one surface and in the pores of the porous polymer separation membrane, wherein the porous polymer actuator has a gradient wherein the amount of the conductive polymer coated in the pores decreases from the one surface of the porous polymer separation membrane toward the other surface.

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.
