Cellulose nanocrystals are tiny, rod-like particles sourced from natural materials. Cellulose nanocrystals that are derived from wood pulp and have dimensions of approximately 5 nanometers (nm) in diameter and 150-200 nanometers in length. Larger crystals can be produced using cotton (10 nm by 500 nm) or algae (20 nm by 1000nm).
Cellulose nanofibrils are noticeably longer and often branched or forked, with dimensions of 20-50 nm in width and lengths of up to several hundred microns. All of the cellulose nanomaterials produced by the UMaine PDC and by our partners at the Forest Products Laboratory are made from wood pulp.
Precautions when Handling – Exercise caution when handling CNC or CNF samples, as the dry material can get dispersed in the air fairly easily. We recommend using a good cartridge-type respirator.
Material Requests – To order samples, visit our Order Nanocellulose page, where you can fill in our Nanocellulose Request Form.
