GLİOKSİLİK ASİDİN İNDİRGEN OLARAK KULLANILDIĞI ELEKTROSUZ BAKIR KAPLANMIŞ POLİESTER KUMAŞLARDA POTASYUM FERROSİYANATIN ETKİSİ

In this study, electroless copper plating on polyester fabric using glyoxylic acid and potassium ferrocyanide (K4Fe (CN) 6) as reducing agent and brightener agent, respectively. Influence of concentration of potassium ferrocyanide (K4Fe (CN) 6) in the plating solution on the deposited rate, morphology and surface resistance of copper plated polyester fabrics were studied. It was found that the deposition rate significantly decreased with the rise of the concentration of K4 Fe (CN)6 and the copper deposits became more compact and smoother. The copper coating on the fabric exhibited a face centered cubic crystal structure. The surface electrical resistance of the obtained copper plated fabric was 13.8 mΩ/sq when 20 mg/L K4Fe(CN)6 was added in the plating solution. The copper plated fabric possesses excellent electrical conductivity
