Wood has been recognized for centuries throughout the world for its versatile and attractive engineering and structural properties. However, like other biological materials, wood is susceptible to environmental degradation. Deterioration of wood in natural weathering process involves very complex combination of chemical, mechanical and light energy factors contribute to what is described as weathering. In this review, the influence of outdoor weathering on the macroscopic, microscopic, chemical and physical changes was described. The mechanisms of photodegredation and protection of wood surfaces are summarized. |
