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.

用于木材防腐的香兰素/二氧化硅微胶囊

香兰素是一种抗真菌和环保的化合物。在这项研究中，使用溶胶-凝胶法将香兰素和二氧化硅微胶囊 (VSM) 微囊化，然后浸渍到木材中。扫描电子显微镜 (SEM)、能量色散 X 射线分析 (EDXA) 和透射电子显微镜 (TEM) 用于表征 VSM 在木材中的形态结构和分布。傅立叶变换红外光谱 (FTIR) 用于研究 VSM 与木材之间的分子间相互作用。评估了经 VSM 处理的木材的抗真菌性能。研究表明VSM具有良好的缓释性能和抗腐烂性。经过 VSM 处理的木材在浸出和暴露于杂色栓菌(L.) 奎尔。和炭疽病菌（个人）Murrill 从对照组的 20.8% 和 15.9% 的质量损失分别减少到 9.2% 和 6.4%。VSM 处理破坏了菌丝体云芝和G. trabeum, 抑制了它们的呼吸代谢和木素酶-漆酶活性云芝. 同时，经 VSM 处理的木材的 MOR 和 MOE 分别为 96.7 MPa 和 12.3 GPa，分别比对照组高 28.8 % 和 11.5 %。
