Nanotechnology can enable the development of a wide range of new or enhanced wood-based materials and products that offer cost-effective substitutes for nonrenewable . Wood and other lignocelluloses are heterogeneous natural polymer composites with large variations in physical and chemical properties. These natural materials are composed of cellulose, lignin, and hemicelluloses. The potential use of nanotechnology for wood science is to modify the properties of wood and wood-based products. Nanotechnology has the potential to affect the field of wood preservation through the creation of new and unique metal biocides with improved properties, treatability of wood species, Water repellent, Environmentally friendly, Overall appearance ,Easy to clean/self cleaning properties ,Weather protection , Chemical resistant ,UV-Stable, Anti bacterial paints , Permanent anti fungal properties. With the help of nanotechnology and nanotechnological products, it is possible to increase the efficiency of the use of raw materials and energy over the life cycle of a product and thus reduce the emission of pollutants as well as energy consumption.
