Description
Since their first isolation in 1940s by Randy, nanocrystalline cellulose attracted the attention of the materials science community. Later during 1980s, the Turbark group succeeded in extracting a new kind of cellulosic nanomaterials in the form of fibrils, stimulating further the interest toward these renewable building blocks. Nowadays, with the emergence of the green portfolio, numerous efforts are being focused on the use of materials from renewable resources, and we are attesting an unprecedented interest for nanocellulose. This interest is due to their renewability and biodegradability, in addition to their appealing intrinsic properties such as low density and outstanding mechanical properties. Moreover, nanocelluloses possess remarkable optical properties originating from their ability to self-organize into liquid crystalline arrangements. All these notable properties allow the use of nanocelluloses in a wide range of applications. This review, not meant to be exhaustive, collates key up-to-date data related to the processing, morphology, and examples of their application in different domains.
