Electromagnetic shielding particleboard with nickel-plated wood particles

We investigated the production of wooden materials with electrical and effe ctive electromagnetic shielding properties. Wood particles metallized by el ectroless plating were suitable as a raw material for the manufacture of pa rticleboard. The specific gravity of the particleboard was about half that of plastic composite materials. We observed a correlation between the surfa ce resistivity of the metallized wood particles and the volume resistivity and shielding effectiveness of the particleboard. The shielding effectivene ss of the particleboard was improved by increasing the quantity of metalliz ed wood particles and the applied pressure.
