Preparation of Copper-coated Polyester Fabric via Electroless Plating Using Glyoxylic Acid as Reducing Agent

Abstract

An environmental-friendly electroless copper plating process was employed in preparing copper-coated\r polyester fabric with excellent conductivity. The effects of bath temperature on the plating rate,\r compositions and crystal structure of the electroless copper deposits were studied. The results showed\r the deposition rate increased with the rise of the bath temperature. X-ray Diffraction (XRD) scan\r indicated that the copper coating deposited was well crystallized and Scanning Electron Microscopy\r (SEM) scan showed copper coating had good surface morphology. Surface resistance of copper plated\r polyester fabric was evaluated. The surface resistance was 16.5 m\u03a9/sq as the temperatue was 65 \u00a0\u00baC.
