Metallization of polyester fabric by autocatalytic copper plating process using glyoxylic acid as a reducing agent

摘要

In this study, metallization of polyester fabric was studied by autocatalytic copper plating using glyoxylic acid as a reducing agent. Surface morphology, composition, and crystal structure of copper coating on polyester fabrics after electroless deposition were characterized by scanning electron microscopy (SEM), energy dispersive X-ray (EDX) analysis, and X-ray diffraction (XRD), respectively. Surface resistance and electromagnetic interference shielding effectiveness (EMI SE) of copper plated polyester fabric were evaluated. It is found that the surface resistance was 128 m Omega/sq and EMI SE arrives at 40-50 dB at the frequency of 6 GHz to 18 GHz as the concentration of copper sulfate was 11 g/l.
