摘要

摘要香兰素是一种抗真菌、环境友好的化合物。本研究采用溶胶-凝胶法将香兰素和二氧化硅微胶囊(VSM)微胶囊化,然后浸渍到木材中。采用扫描电子显微镜(SEM)、能谱X射线分析(EDXA)和透射电子显微镜(TEM)对木材中VSM的形态结构和分布进行了表征。利用傅立叶变换红外光谱(FTIR)研究了VSM与木材的分子间相互作用。对VSM处理木材的抗真菌性能进行了评价。研究表明,VSM具有良好的缓释性能和耐腐性。VSM处理的木材在浸出和暴露于云芝后的质量损失。和Gloephyllum trabeum(Pers.)Murrill从20.8的质量损失减少 % 和15.9 % 对照组的9.2 % 和6.4 %, 分别地VSM处理破坏了云芝和trabeum的菌丝体,抑制了它们的呼吸代谢,并抑制了云芝的木质素酶-漆酶活性。同时,VSM处理木材的MOR和MOE分别为96.7 MPa和12.3 GPa为28.8 % 和11.5 % 高于对照组。

Vanillin/silica microencapsulation for wood preservation
Abstract Vanillin is an antifungal and environmentally friendly compound. In this study, vanillin and silica microcapsules (VSM) were microencapsulated using the sol-gel method and then impregnated into wood. Scanning electron microscopy (SEM), energy-dispersive X-ray analysis (EDXA) and transmission electron microscopy (TEM) were used to characterize the morphological structure and distribution of VSM in wood. Fourier transform infrared spectroscopy (FTIR) was used to study the intermolecular interactions between VSM and wood. The antifungal performance of the VSM-treated wood was evaluated. The study revealed that VSM had good sustained-release performance and decay resistance. Mass losses of VSM-treated wood after leaching and exposure to Trametes versicolor (L.) Quel. and Gloephyllum trabeum (Pers.) Murrill decreased from mass losses of 20.8 % and 15.9 % of the control group to 9.2 % and 6.4 %, respectively. VSM treatment disrupted the mycelium of T. versicolor and G. trabeum, inhibited their respiratory metabolism, and the ligninase-laccase enzyme activity of T. versicolor. Meanwhile, MOR and MOE of VSM-treated wood were 96.7 MPa and 12.3 GPa which were 28.8 % and 11.5 % higher than the control group, respectively.
