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...
