采用真空加压浸注法将三聚氰胺甲醛（MF）溶胶填充于木材内部，并经超临界干燥可得MF 气凝胶-木材复合材。扫描电镜（SEM）显示，MF 气凝胶在木材内部呈三维网络结构，X 射线衍射仪（XRD）分析结果表明，MF 气凝胶的填充也对木材的结晶特性并无破坏。傅里叶变换红外光谱仪（FTIR）分析表明，MF 气凝胶和木材之间可通过化学实现有机结合，制备的复合材热稳定性有较大提高。对MF 气凝胶/木材复合材的物理力学性能的检测分析表明，其具有良好的尺寸稳定性、优良的力学性能和热稳定性。
Wood/melamine-formaldehyde (MF) aerogel composite was obtained by vacuum impregnation and drying with supercritical fluids. The result of scanning electron microscopy shows that MF aerogel in the wood has a network structure. The result of X-ray diffraction indicates that the filling of MF aerogel in the wood would not destroy the crystallization structure of the latter. Because of chemical bonding between MF aerogel and the wood, which was proved by Fourier transform infrared spectroscopy, the resulting composite has better heat resistance. The analysis of the physical and mechanical performance of the composite shows that it has satisfactory dimensional stability and mechanical properties.
