In the context of the acceleration of the global 'double carbon' strategy and green manufacturing, bio-based materials are becoming the core direction to break resource constraints and reduce environmental pressure. Among them, bacterial cellulose (BC), with its unique nanoscale network structure, excellent physical properties and sustainable characteristics, stands out from many cellulose materials and has become a 'potential stock' that has attracted much attention in the field of new materials. As a natural polymer synthesized by microbial fermentation, bacterial cellulose is realizing large-scale applications in the fields of medical health, food industry, environmentally friendly packaging, flexible electronics and other fields with its core advantages of 'high purity, excellent strength, biocompatibility, and degradability', providing new solutions for the upgrading of traditional industries and the development of emerging industries. 1. Core understanding: The essence and unique properties of bacterial cellulose. Bacterial cellulose is produced by Acetobacter genus (such as Komagataeibact

1. Nanocellulose: From natural polymers to high-performance functional materials Nanocellulose (Nanocellulose) is a nanoscale material prepared from natural cellulose through mechanical dissociation, chemical modification (such as TEMPO oxidation) or enzymatic treatment. It is mainly divided into: CNF (Cellulose Nanofiber) nanocellulose fiber CNC (Cellulose) Nanocrystal) Nanocellulose crystal is essentially a linear polysaccharide material with a highly ordered structure, showing significant performance transitions at the nanoscale: ▶ Core structure advantages Structural features Corresponding performance Nanoscale diameter (5–50 nm) High specific surface area (>200 m²/g) High crystalline area ratio Excellent mechanical strength (modulus up to 140 GPa) Rich hydroxyl/carboxyl groups Easy surface functionalization Three-dimensional network structure Excellent film-forming properties and
