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

As the dual-carbon policy continues to be implemented, plastic restriction regulations continue to tighten, and the global industrial chain is accelerating away from dependence on petroleum-based raw materials, safe, renewable, and fully degradable new bio-based materials have become an urgent need for the transformation and upgrading of all walks of life. Many formulation engineers and material manufacturers are looking for functional fillers that can take into account performance, safety and environmental protection. Nanocellulose (CNF) is the natural nanobiomass material with the fastest commercialization speed and the most abundant application scenarios. Nanocellulose is extracted from natural plant fibers such as bamboo, wood, cotton linters, agricultural and forestry straw, etc. It relies on green processes such as mechanical dissociation, enzymatic pretreatment, and modification control to disassemble macro fibers to the nanometer scale. Different from ordinary cellulose derivatives, it retains the natural cellulose skeleton structure and does not rely on the synthesis of petrochemical raw materials. The production process is low-pollution, and the finished product is non-toxic and non-irritating. It can be completely recycled in the natural environment after being discarded.

Nanocellulose (CNF) is a biomass nanomaterial prepared from natural plant fibers through nanodissociation. With its unique advantages such as high specific surface area, excellent mechanical strength, film-forming, modifiable, renewable, and biodegradable, it has shown great industrialization potential in new energy storage and flexible electronics. The long-lasting suspension effect of coffee powder that we demonstrate daily is the rheological properties brought about by the three-dimensional network structure of nanocellulose. In the new energy and flexible electronics scenarios, its high-strength film and porous network structure provide new material solutions for the new generation of low-carbon electronics and energy storage devices. 1. In the context of dual carbon applications in the field of new energy storage, industries such as lithium batteries, sodium batteries, supercapacitors, and perovskite photovoltaics continue to pursue higher safety, longer cycle life, and lightweight. Nanocellulose, as a biomass functional material, achieves technological empowerment in separators, electrode substrates, solid electrolytes, photovoltaic substrates, and other links. 1.
