Research Abstract

A cellulose aero-gel like agar was obtained bytreating cellulose jelly that was prepared by mixing chemicals and cellulose extracted from wood, rice straw and other cellulose sources, with dry carbon dioxide fluid. The cellulose aero-gel made from pure and large cellulose molecule was hard and had nano-pore uniformly distributed in it. Composite of the aero-gel and acrylic plastic was also obtained.
