Method assembles cellulose nanofibres into a material stronger than spider silk

Researchers at KTH have produced a bio-based material that is reported to surpass the strength of all known bio-based materials whether fabricated or natural, including wood and spider silk.

Working with cellulose nanofibre (CNF), the essential building block of wood and other plant life, the researchers report that they have overcome the difficulty in translating the incredible mechanical properties of these nanofibres into larger, lightweight materials for use in airplanes, cars, furniture and other products.
