In this paper, the spectroscopic and morphological behaviors of nylon 6-copper chloride systems have been investigated. The temperature-variable Fourier transform infrared (FT-IR) spectra of nylon-copper chloride systems shows that a new band of 1600 cm(-1) appeared between the amide I band at about 1639 cm(-1) and the amide II band around 1552 cm(-1) compared with the FT-IR spectra of pure nylon, which indicates that there was the coordination between copper ions and the amide groups of nylon. The processed spectra of extended X-ray absorption fine-structure of copper ions at K edge showed that one copper ion can coordinate two oxygen atoms and two chloride ions in nylon 6-copper chloride systems, Phase separation in nylon-copper chloride systems was observed by using near-field scanning optical microscopy.
