Cellulose nanofibrils (CNF), also known as nanofibrillated cellulose (NFC) or microfibrillated cellulose (MFC), are cellulose-based materials characterized by their expanded volume, moderate degradation, and significantly increased surface area. These nanofibrils are typically produced through homogenization processes, resulting in diameters ranging from 20 to 60 nanometers and lengths extending several micrometers. Unlike cellulose nanocrystals (CNC), CNFs comprise both amorphous and crystalline regions, forming a web-like structure. At low concentrations (2–7% by weight), CNFs form viscous, shear-thinning aqueous gels and can create transparent films upon drying. These properties are attributed to their high specific surface area—at least ten times greater than that of traditional cellulose fibers—and extensive hydrogen bonding capabilities. The flexibility, length, and large surface area of CNFs make them suitable for various applications, including food additives, biodegradable packaging, pigments, selective delivery and separation processes, nanocomposites reinforced with polymers, as well as medical and pharmaceutical uses.
Reinste offers a range of CNF products derived from sources such as bleached softwood kraft pulp, bleached hardwood kraft pulp, kenaf pulp, and dissolving-grade cotton pulp. These nanofibrils are prepared using high-pressure homogenizers or supermass colloiders and are available in forms like aqueous gels (0.5–5% solids), white powders, or flexible aerogels. The product lineup includes unmodified CNFs, cationically modified CNFs, carboxymethylated CNFs, and anionic CNFs. Notably, CNF aqueous gels exhibit no hard agglomeration and can be redispersed in water after freeze-drying or spray-drying using high-speed homogenizers or supermass colloiders.
