Nanocellulose in Paper and Board provides information on structure and properties, raw materials, production and characterization methods, surface treatment, and applications in paper, board and high-strength composites.

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.
