EFFECTS OF Pd2+ CONCENTRATION ON THE STRUCTURAL PROPERTY OF NICKEL-PLATED PLANT FIBER NON-WOVEN SHEET

Abstract

In this work, a facile method combined with PdCl2 solution immersing and electroless deposition to fabricate nickel-plated plant fiber non-woven sheet is demonstrated. The effect of [Formula: see text] concentration on the structural property of plated sheet was investigated using X-ray photoelectron spectroscopy, X-ray diffraction and scanning electron microscopy. Results showed that increasing activated time and PdCl2 concentration would facilitate the enhancement of Pd-adsorbed amount on the substrate surface. It would facilitate the deposition of nickel atom, the reduction of the surface electrical resistivity and the crystallization of plated coating due to the high catalytic sites. In addition, the lowest PdCl2 effective concentration was reduced with the increased of activated time.
