A novel polymer based antimicrobial coating with embedded copper or copper salt particles

This research is to develop a composite coating which can provide good antimicrobial property and compatibility with none-metallic substrates. The paper reports an innovative polymer based coating system containing mixtures of fine particles of copper (Cu) and Cu salt. This composite coating was o...

description This research is to develop a composite coating which can provide good antimicrobial property and compatibility with none-metallic substrates. The paper reports an innovative polymer based coating system containing mixtures of fine particles of copper (Cu) and Cu salt. This composite coating was obtained by an aqueous colloid paste which is formed by mixing fine particles of Cu and Cu salt (Cu sulphate and Cu chloride) with epoxy resin Nuplex K36. Atom absorption spectroscopy was used to measure the concentration of Cu ion which is released from the coatings. The antimicr~bi~l properties we.re studied by bactericidal test against Escherichia coli (E. coli) ATCC25922. Transmission electron mIcroscopy (TEM) was performed to characterize the change of E. coli after contac~ing with the .coatings. Syn~hrotron Infrared microscope (SRIRM) was used to in-situ and in-vivo study the Impact of C~ Ions.on bactena. The coating with embedded fine Cu salt showed higher antimicrobial property th~n th~ coatmg WIth.~u due to releasing more Cu ions. Single bacterial cell membrane changes can be clearly identified by combmmg TEM and SR-IRM technique, which provide an explanation of the mechanism of Cu coating antimicrobial property.
