Abstract

This research focuses on increasing wood resistance against UV degradation using trimethoxyphenylsilane as modifying agent and supercritical CO2 as a green solvent and reaction medium. Trimethoxyphenylsilane was successfully grafted on European spruce (Picea abies, H. Karst) and was characterized by SEM-EDX and UV–vis reflectance. SEM-EDX showed the presence of silicium inside the wood cell wall. Increased wood moisture content showed positive effect on weight gain of trimethoxyphenylsilane after treatment. UV resistance of treated wood was evaluated by following the color change during artificial weathering. Modified samples showed improved weathering resistance compared to unmodified wood with a ΔE value around 5 after 260 h. Processing and modifying wood using supercritical CO2 is a promising route to increase wood performances and increase its use as a building material.

通过超临界二氧化碳对木材进行三甲氧基苯基硅烷改性以增强耐候性
以三甲氧基苯基硅烷为改性剂,超临界CO2为绿色溶剂和反应介质,研究提高木材抗紫外线降解能力的方法。将三甲氧基苯基硅烷成功地接枝在欧洲云杉(Picea abies, H. Karst)上,并用SEM-EDX和紫外-可见反射率对其进行了表征。SEM-EDX显示木材细胞壁内有硅的存在。处理后木材含水率的增加对三甲氧基苯基硅烷增重有积极影响。通过观察人工风化过程中木材的颜色变化来评价木材的抗紫外线性能。与未改性木材相比,改性样品在260 h后的耐候性得到了改善,其ΔE值约为5。使用超临界二氧化碳对木材进行加工和改性是提高木材性能和增加其作为建筑材料用途的有希望的途径。
