METHOD FOR PREPARING POLYANILINE COMPOSITE FOR ANTIBACTERIAL USE AND HEAVY METAL REMOVAL, IN WHICH ORGANIC ACID AND METAL IONS ARE DOPED INTO POLYANILINE CONDUCTIVE POLYMER IN PREDETERMINED ORDER, AND POLYANILINE COMPOSITE PREPARED BY SAME METHOD

摘要

The present invention relates to a method for preparing an insoluble polyaniline composite for antibacterial use and heavy metal removal, wherein an organic acid is doped into a porous non-conductive polyaniline emeraldine base to give conductivity thereto and then metal ions are doped thereinto, so the metal ions are attached on a conductive polymer surface, and to a polyaniline composite prepared by the method. The polyaniline composite has excellent effects of adsorbing or removing bacteria and microbes and removing heavy metals, and thus can be variously applied, for antibacterial use and heavy metal removal, to a water purifier filter, an automobile or domestic air-conditioner filter, an air conditioner, a gas mask, a drinking water and sewage treatment device, an air purifier, a clean room, and the like.
