Polymeric Fungicides in Wood Preservation

as one of the most important natural resources, supplies structural material for many objects necessary to everyday life. Wood, hard or soft, can be successfully used in manufacturing windows and doors, furniture, and wood floors. The hard woods have generally higher density and modulus than soft woods resulting in a heavier and stiffer product. It is important to modify wood to improve wood properties as strength, appearance, resistance to penetration by water and chemicals, and resistance to decay. 

Wood can be modified by treating with orgaific biocides which have low solubility in water and their organic solution can be dispersed in water using surfactants to stabilize a mostly aqueous liquid-in-organic liquid emulsion. Controlled release formulations of antifouling moieties have been used for the protection of wood against 

Wood is susceptible to many forms of degradation, especially when it is exposed to fungi and insect species as termites, powder post beetles, and carpenter ants which are wood-destroying organisms. This was the original idea behind the development of wood preservatives by destroying wood-insects, and various chemicals have been used for wood treatment. The chemicals used extensively for wood protection and as insect repellents for wood preservatives include pentachlorophenol, arsenic 

Wood-polymer composites are claimed to be superior to natural wood and have several advantageous features (1) natural abundant, cheap and renewable agrofibers. 

The wood-polymer composite industry has the greatest growth potential in building products that have limited structural requirements and the materials selected depend very much on the intended end product and cost, availability, market value, and product performance requirements. The main composite product is decking or splintering [304]. Other areas of activity are outdoor furniture such as picnic tables, park benches, naturetrails/walkways, fencing piers, boardwalks, window and door
