Naturally
derived nanocellulose (NC) is a renewable, biodegradable
nanomaterial with high strength, low density, high surface area, and
tunable surface chemistry, which allows its interaction with other
polymers and nanomaterials in a controlled manner. In recent years,
NC aerogel has gathered a lot of attention due to environmental concerns.
This review presents recent developments of NC-based aerogels and
their controlled interactions with other polymers and nanomaterials
for thermal applications that include electronic devices, the apparel
industry, superinsulating materials, and flame-retardant smart building
materials. After going through the distinctive properties of NC aerogels,
they are orderly categorized and discussed as thermally insulated,
thermally conductive, and flame-retardant materials.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
