摘  要:
根据木材的天然生物结构,利用木材改性的方法对气凝胶型木材的制备进行了初步研究,以期在解决气凝胶在实际应用方面存在的一些缺陷的同时赋予木材新的功能,使木材功能性改良体现木材和纳米材料的双重优点。分别使用A,B两种溶液对木材进行改性处理,并通过CO2超临界流体干燥后,再使用扫描电子显微镜(SEM)、傅立叶红外光谱仪(FTIR)、X射线衍射仪(XRD)对处理试件进行表征。

摘  要:
A study was conducted to prepare aerogel-type wood by using wood modification methods according to the natural biological structure of wood aiming to solve the defects of aerogels in practical applications and to endow the wood with some new functions.In the experimental process,two kinds of solutions were used to modify the wood and then the wood was dried by the supercritical fluid drying technique.Moreover,SEM,FTIR and XRD were used to study the characteristics of the wood samples.
