Polyester fabric was catalyzed with Nickel(II) acetylacetonate (Ni(acac)2) in supercritical carbon dioxide (scCO2) prior to electroless copper plating. The nickel activated polyester fibers were then characterized by scanning electron microscopy and X-ray photoelectron spectroscopy. Deposited weight, surface morphology, crystal structure, surface resistance, electromagnetic interference shielding effectiveness and thermal loss of the copper plated polyester fabrics catalyzed with nickel in scCO2 were investigated. The results indicate that the amount of copper deposited onto polyester fabric catalyzed with Ni(acac)2 in scCO2 is much more than that without scCO2. Deposition rate of copper particles onto polyester fabric increases with increased temperatures of scCO2. The copper particles are uniformly coated on the polyester fibers. The surface resistance of the copper plated fabric is 50 mΩ/sq when the temperature of scCO2 is increased to 90 °C. The electromagnetic interference shielding effectiveness of the copper plated polyester fabric is 60–80 dB at frequencies ranging from 2 to 18 GHz. These results suggest that catalysis in scCO2 for electroless copper plating provides polyester fabric with excellent electrical conductivity, surface resistance and electromagnetic interference shielding effectiveness.
