Preparation and Kinetics of Wood-Based Ni-P Coating Electromagnetic Shielding Material by Ytterbium-Improved Electroless Plating

Abstract:

A wood-based Ni-P coating electromagnetic shielding material was prepared in an ytterbium oxide-added electroless plating bath. The kinetic model was established and confirmed to be in accord with the experiment and can be used to predict the deposition rate within a certain range. The experimental results showed that the Ni-P coating prepared with the addition of Yb₂O₃ were smoother, denser and brighter than that prepared without addition of Yb₂O₃. The deposition rate and electromagnetic shielding effectiveness of the former were 2.662mol×10^-4/(cm²h) and 56.48 dB which is about 13% and 9% higher than those of the latter under the same bath compositions and operation conditions.
