Preparation of Copper Sulfide Deposition on Modified Poly(Ethylene Terephtalate) Fibres with Good Conductivity

The immobilization of CuS on the surface of poly (ethylene terephtalate) (PET) fibres was carried out by the functionalization of PET fibres with chitosan (CS), followed by the chemical deposition method. Crosslinked chitosan with NH2 functionality was used as a chelator to absorb copper ions, which can successfully initiate CuS deposition in the following chemical deposition stage. The CuS-loaded fibres were characterised by scanning electron microscopy, X-ray diffraction, infrared spectroscopy and thermal gravimetry, respectively. The properties of tensile and conductivity were also investigated. The lowest surface resistance 42 Ω/cm of the treated PET fibres was obtained when the CS concentration was 1.0%.
