Abstract: A material containing cellulose nanofibres, the material comprising a gel material comprising cellulose nanofibres in an aqueous medium, the cellulose nanofibres having 10% or more by weight hemicellulose. The cellulose nanofibres have a diameter of less than 100 nm, or less than 50 nm, or less than 20 nm. The gel material can be used as an adhesive to make laminates or to make paper by dewatering the gel material.

Abstract: A nanocellulose material of plant origin comprising nanocellulose particles or fibres derived from a plant material having a hemicellulose content of 30% or higher (w/w) (calculated as a weight percentage of the lignocellulosic components of the material). The nanocellulose may have an aspect ratio of greater than 250. The nanocellulose may be derived from plant materials having C4 leaf morphology. The plant material may be obtained from arid Spinifex. The nanocellulose can be made using mild processing conditions.

Abstract: Disclosed are injectable compositions. Such compositions may be formed from cellulosic fibers and a deep eutectic solvent. Also disclosed are methods of preparing an injectable composition, which comprises: (i) contacting cellulosic fibers with a deep eutectic solvent to provide deep eutectic solvent treated cellulosic fibers; (ii) washing the deep eutectic solvent treated cellulosic fibers; and (iii) homogenizing or mechanically refining the washed deep eutectic solvent treated cellulosic fibers to thereby provide the injectable composition. Also disclosed are uses of the compositions and methods involving the compositions.

Abstract: A composite material comprising an elastomer and nanocellulose. The nanocellulose may comprise a nanocellulose material derived from plants having C4 leaf anatomy, or a nanocellulose material derived from a plant material having a lesser amount of lignin than hemi-cellulose, or a nanocellulose having a hemicellulose content of from 25% to 55% by weight of the nanocellulose material, or a nanocellulose comprising nanofibrils having a diameter of up to 5 nm, or a nanocellulose comprising nanocellulose material of plant origin comprising nanocellulose particles or fibres having an aspect ratio of at least 250, or the composite material having a stiffness of not greater than 2.5 times the stiffness of the elastomer without the nanocellulose material being present, or the nanocellulose particles or fibres being derived from a plant material having a hemicellulose content of 30% or higher (w/w). The nanocellulose may be derived from arid Spinifex.
