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.

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.
