Use of modified nanoparticles in wood materials for reducing the emission of volatile organic compounds (VOCs)

摘要

The present invention relates to the use of modified nanoparticles in wood based panels, in particular OSB-panels for reduction of the emission of volatile organic compounds (VOCs). The invention further relates to a wood based panel containing the modified particles and to a method for producing such a wood based panel.
