Method for preparing polyaniline complex with antimicrobial activity and heavy metal removal efficiency using conductive poly aniline polymer doped with organic acid and metal ion in defined order

摘要

Disclosed is a method for preparing an insoluble polyaniline complex with antimicrobial activity and heavy metal removal efficiency that involves doping a porous nonconductive polyaniline emeraldine base with an organic acid to impart conductivity and then with a metal ion to render the metal ion attached to the surface of the conductive polymer, and a polyaniline complex prepared from the preparation method, which polyaniline complex is excellent in the ability to adsorb and/or eliminate bacteria and other microbes and to remove heavy metals and hence available in any of various applications for antimicrobial activity and heavy metal removal, including filters for water purifier, automobile or household air conditioner, gas masks, water and sewage treatment system, air purifier, cleanroom, etc.
