Abstract
This chapter describes the industrial perspectives of cellulose-based porous materials or aerogels. These nanostructured materials have high degree of applicability in many industry relevant technologies. The presence of strong intra- and inter molecular hydrogen bonding in cellulose structures results the formation of a cross-linking network of an aerogel. An aerogel combines high degree of porosity and surface area with superior mechanical properties and processability. In addition to these assets, nanocellulose-based aerogels show excellent biodegradability and biocompatibility. The present chapter deals with the extraction of cellulose nanofibers and nanocrystals besides discussing the difference between a cellulose-based aerogel and a cellulose-based paper. The technology variant applications of cellulose-based aerogels such as in the field of thermal insulation, flame retardance, biomedical, and oil adsorption are discussed in detail.
