Nanocellulose (NC) is a biomass nanomaterial prepared from natural plant fibers through green pretreatment and nanodissociation processes. It mainly includes three categories: cellulose nanofibrils (CNF), cellulose nanocrystals (CNC), and bacterial cellulose (BC). It is hailed by the industry as a super new material in the green era. Cellulose is the most abundant natural polymer on earth, with an annual biological output of hundreds of billions of tons. It comes from a wide range of sources and is renewable. We rely on an independent and controllable green preparation process to strip natural fibers down to the nanometer scale. The fiber diameter can reach tens of nanometers, retaining a large number of active hydroxyl structures, while giving the material a series of unique excellent properties: high aspect ratio, ultra-large specific surface area, ultra-high Young's modulus, light weight and high strength, low expansion coefficient, good light transmittance; at the same time, it has excellent biocompatibility, is completely biodegradable, non-toxic and safe, and can be surface modified

Nanocellulose (CNF, cellulose nanofibrils) is a nanoscale natural fiber material extracted from wood pulp and agricultural and forestry biomass. It is a biodegradable and environmentally friendly nanomaterial. With its high specific surface area, high strength, excellent rheological thickening, suspension stability, film-forming barrier and other characteristics, nanocellulose is replacing some petrochemical raw materials and becoming a popular green functional additive in daily chemicals, food, papermaking, coatings, composite materials, biomedicine and other fields. Nanjing Tianlu Nanotechnology is deeply involved in the industrialization of nanocellulose and can provide standardized products and customized carboxylation modification solutions to support the docking of samples and technology. 1. What is nanocellulose? Definition and Classification of Nanocellulose Nanocellulose is a one-dimensional nanofiber material prepared from natural cellulose through mechanical dissociation, chemical modification and other processes. It is mainly divided into three categories: 1. CNF cellulose nanofibrils: long fiber network structure, outstanding rheology, thickening, and suspension capabilities.

Nanocellulose is a type of cellulose material that uses natural plant fibers such as wood and bamboo as raw materials and is dissociated to the nanometer scale through physical, chemical or biological means. As an important direction for high-value utilization of biomass resources, it relies on the natural molecular structure of cellulose itself and combines the unique effects brought about by the nanoscale, and has become a hot spot for continuous research in the field of materials in recent years. Nanjing Tianlu Nanotechnology has long carried out basic research on the preparation, characterization and application of nanocellulose, and continues to explore the industrialization path of this type of bio-based materials. 1. Main classification of nanocellulose According to differences in preparation methods, morphology and structure, mainstream nanocellulose can be divided into three categories: Cellulose nanofibrils (CNF), which is also the most widely explored category at present. It retains long fiber chain segments, has a large aspect ratio, and is easy to form an intertwined three-dimensional network structure. It has outstanding rheological properties and film-forming properties. It is also the product system we focus on. cellulose
