Background: Wood science and nanomaterials science interact together in two different aspects;
a) fabrication of lignocellulosic nanomaterials derived from wood and plant-based sources and
b) surface or bulk wood modification by nanoparticles. In this review, we attempt to visualize the
impact of nanoparticles on the wood coating and preservation treatments based on a thorough
registration of the patent databases.
Method: The study was carried out as an overview of the scientifically most followed trends on
nanoparticles utilization in wood science and wood protection depicted by recent universal filed patents.
This review is exclusively targeted on the solid (timber) wood as a subject material.
Results: Utilization of mainly metal nanoparticles as photoprotection, antibacterial, antifungal, antiabrasive
and functional component on wood modification treatments was found to be widely patented.
Additionally, an apparent minimization in the emission of volatile organic compounds (VOCs) has
Conclusion: Bulk wood preservation and more importantly, wood coating, splay the range of strengthening
wood dimensional stability and biological degradation, against moisture absorption and fungi respectively.
Nanoparticle materials have addressed various issues of wood science in a more efficient
and environmental way than the traditional methods. Nevertheless, abundant tests and regulations are
still needed before industrializing or recycling these products.
