Abstract:

Continuous and uniform layer of Nickel was obtained on the surface of birch veneer through electroless plating in order to produce wood-metal composite which has electromagnetic shielding properties. It was shown by SEM photos that the surface of birch veneer as if smooth was actually very coarse and the structure of the surface which looked like metal very much didn't change after plated. It was shown by EDS and XPS that the main element was Nickel and the content of P was very low in the layer which is microcrystalline structure by XRD analysis. Electromagnetic shielding effectiveness of the wood-metal composite is up to 60 dB at frequencies from 9 kHz～1.5 GHz, and it's electroconductivity and thermal conductivity were improved much.

Key words: birch veneer, electroless Nickel plating, composition of the layer
