Microstructure of Wood Cell Wall and Preparation Principle of Aerogel-type Wood

Gao Jingran,Qiu Jian(Faculty of Wood Science and Decoration Engineering,Southwest Forestry University,Kunming 650224,P.R.China);Li Jian,Liu Yixing(Key Laboratory of Bio-based Material Science and Technology,Ministry of Education(Northeast Forestry University)  
The chemical composition and ultra-microstructure of wood cell wall and the structure of wall layer are expatiated.According to the structure of wood cell wall,the preparation of aerogel-type wood mainly includes three steps,namely the destruction of wood cell wall in S3 layer,the expansion of wood cell wall and supercritical drying.The preparation steps of aerogel-type wood are briefly described in terms of the basic principle.
