Electromagnetic Shielding Particleboard with Nickel-Plated Wood Particles

We investigated the production of wooden materials with electrical and effective electromagnetic shielding properties. Wood particles metallized by electroless plating were suitable as a raw material for the manufacture of particleboard. The specific gravity of the particleboard was about half that of plastic composite materials. We observed a correlation between the surface resistivity of the metallized wood particles and the volume resistivity and shielding effectiveness of the particleboard. The shielding effectiveness of the particleboard was improved by increasing the quantity of metallized wood particles and the applied pressure.
