英文摘要： Since most of straws contain hydrophobic waxy cuticle layers and a high amount of inorganic silica which results in weak bonding between particles, many attempts have been made to improve the bondability between the straw materials and adhesives through raw material pretreatment. The objective of this project is to explore an innovative means - plasma treatment which can form an active nano-scale surface on straws and enhance the bonding strength of straws. The influence of plasma treatment methods and parameters on the characteristics of the nano-scale surface on straws and the bondability between the straw materials and adhesives will be investigated, so that the mechanism of forming the nano-scale surface on straws and improving the bonding strength of straws by plasma treatment can be clarified. Finally, the plasma treatment which can be applied in the industrial production line of straw-based panels can be developed in the light of the theoretical and practical achievements from this project. These achievements will promote the value-added applications of straws and the sustainable development of wood industry in China.
