Paper Title:
Preparation of Lignocellulose Aerogel from Wood-Ionic Liquid Solution
  Abstract

This paper reports a new method to prepare a new lignocellulose aerogel that is made from two kinds of wood powder through dissolution/regeneration of cellulose in ionic liquids. The obtained gel was washed with ethanol, liquid carbon dioxide and finally dried by releasing the carbon dioxide from the net structure at supercritical temperature to obtain the aerogel wood. All aerogels were compressible and consisted of nanofibrillar biomaterial network with open-pore structure. The range of density meets a criterion with aerogel density. Infrared spectrum shows that the pre-and post-treatment characteristic absorption peak of wood powder remained unchanged, and the ionic liquid played a mesomeric role among the physical reaction.
