Bio-Based Aerogels: From renewable resources to ultra- light nanostructured materials – Fact Sheet

Bio-aerogels: a new class of versatile and functional biobased materials Bio-aerogels are one of the classes of aerogel materials that exhibit open-porous nanofibrillar network. They are based on natural polymers such as polysaccharides or proteins. Bio-aerogels are produced by sol-gel synthesis via biopolymer dissolution followed by chain self-assembly and drying with supercritical carbon dioxide. No […]
