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.
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.
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 been succeeded.
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.
木材科学与纳米材料科学在两个不同方面相互作用；a）由木材和植物来源制备木质纤维素纳米材料，以及b）通过纳米颗粒对木材表面或整体进行改性。在本综述中，我们试图通过全面检索专利数据库，来展现纳米颗粒对木材涂层和防腐处理的影响。
本研究是对近期全球专利所描绘的木材科学与木材保护中纳米颗粒利用方面最受关注的科学趋势进行的概述。本综述专门针对实木（木材）作为主题材料。
发现主要将金属纳米颗粒用作木材改性处理中的光保护、抗菌、抗真菌、抗磨和功能成分已获得广泛专利。此外，挥发性有机化合物（VOCs）的排放量已明显减少。
木材整体防腐，更重要的是木材涂层，分别在增强木材尺寸稳定性和防止生物降解、防潮和防霉方面发挥作用。纳米颗粒材料比传统方法更高效、环保地解决了木材科学的各种问题。然而，在这些产品实现工业化或回收利用之前，仍需要进行大量测试和制定相关规定。
