Cellulose has great potential as a nanomaterial as it's abundant, renewable and biodegradable. It can be used in paper for its superior strength properties and can also be used as a wet-end additive to enhance retention in coating and packaging applications. Nanocellulose can form transparent films with excellent barrier properties, allowing it to be competitive with petroleum-based plastics in food packaging. Due to its reinforcing properties, nanocellulose can also be used in bio-composites and other matrix materials.
6.9 Concluding remarks
Natural fibres, cellulose and other constituents of natural fibres are very promising materials for the future, having the capability to replace current synthetic materials. with the rapid developments in nanotechnology, nanocellulose brings many new insights to the materials world, such as its modulus value of 160 GPa, which is much greater than metallic materials. Considerim the challenges mentioned earlier, it is rational to predict that immediate applications of nanocellulosic materials can be formulated from water-based polymer matrices, like polyvinyl alcohol, starch/polyvinyl alcohol blends and latexes, by which two major problems can be eliminated. Here, the dispersion is done in the aqueous phase, so the additional step of drying can be omitted and the hydrophobic modification of the nanocellulose materials is not...
