Cellulose aerogels are multifunctional solid materials with low
density, low thermal conductivity, large internal surface area and
high porosity. Their structure can be described as a random threedimensional
network of cellulose fibrils of a few ten nanometers
in diameter. They are promising materials for various applications
such as nanostructured, bio-based materials for thermal
insulators, insulation materials for the aerospace and aviation
industry, storing media for gases in fuel cells, filter materials
for extremely fine particles, drug delivery systems, drug coating
purposes, hygiene products, highly functional fibers in textile
and filtering applications
