Improvements of surface layer by wood modification

An intensive research on the development of materials and methods of application which can improve durability of wood and woodcoatings is being researched during last few years. Wood properties such as dimensional stability, water repellency, resistance to biological attack, UV- and visible light stability and even mechanical properties can be significantly improved by applying chemical and thermal treatments which are the main subject of this work. Wood properties that are mentioned above can be improved by heat treatment, acetylation, plasma treatment or by applying of nano coatings. Heat treated and acetylated wood are already comercialy used abroad, wihle posibilities of comercial usage of other methods need to be investigated. Because of its significantly improved properties, modified wood can be used for cladding and fencing, for noise reduction barriers, joinery and furniture in exterior, and also in flooring and furniture in interior.
