摘要
In this study, an effective deposition of Ni-P alloy on polyester (PET) was proposed by a chemical plating method with PdCl2 solution and a chelating agent chitosan (CTS). As a critical step in chemical plating of making electromagnetic shielding fabric, the optimized processing of textile chemical plating is the fabrics padded with 3% acetic acid (HAc) solution containing 10 g/L CTS and 5.5 mL/L formaldehyde (HCHO) as cross-linking agent for 20 min at room temperature. The highest weight gain and the lowest surface resistance of the treated fabric were achieved by the optimum pretreatment method. The CTS-Pd PET fabrics were characterized by scanning electron microscopy (SEM), scanning probe microscope (SPM), and the glancing incident angle X-ray diffraction (XRD)pattern. The results showed that CTS acting as a chelating had effectively fixed Pd (II) ions. A uniform and continuous structure of Ni-P plating layer was obtained using the CTS pretreatment.
