Abstract

Considering the recent massive usability of plastics that are nonbiodegradable and unsuitable for our environment, our scientists wanted to introduce green technology-based and environmentally friendly products to ensure our global life. In this regard, a most abundant naturally occurring purified plant matter biopolymer, “Nanocellulose,” has been considered for its outstanding properties. It consists of impressive chemical and physical properties, gas inflammable, high infinity to water, biodegradable (not like petroleum), rigid than Kevlar and more robust than steel, it in composites form can be used in electrical and thermally conductive materials. Nanocellulose-based aerogels are one of the attractive fields for researchers because of their extraordinary mechanical properties, low density, large specific surface area, high porosity, low thermal conductivity, and low electrical conductivity. This review consists of structure, source, and method of extraction for nanocellulose, its properties, and applications, as well as the illustration of, in what manner the porous morphology and characteristics of aerogels based on nanocellulose can be adapted for applications such as thermal insulation and energy storage, air filtration, water filtration, precursors of carbon aerogels.
