1. Preface: The intersection of nanomaterials and green technology

In the context of the rapid integration of green materials and nanotechnology, Bacterial Cellulose (BC ), as a nano-level high-performance material naturally synthesized by microorganisms, has gradually become the focus of attention in various high-value-added industries. It not only has the environmental advantages of natural polymer materials, but also due to its unique nanofiber network structure .plays a key role in biomedicine, intelligent manufacturing, food packaging and other fields

2. Source and microstructure of bacterial cellulose

Bacterial cellulose is synthesized by microorganisms such as Acetococcus through metabolic processes under aerobic conditions, forming a three-dimensional network structure composed of This structure shows:fiber filaments with a diameter of 20 to 100 nanometers.

High crystallinity ( 70~90% )

High specific surface area (> 100 m²/g )

Extremely high purity (without lignin or hemicellulose)

Porousity and adjustable pore structure

These nano characteristics are significantly different from plant cellulose, giving bacterial cellulose properties that are incomparable to many traditional materials.

3. Core performance brought by nanostructures

1. High strength and flexibility coexist

The nanofibers form a stable structure through hydrogen bonding, and the material is both tough and supportive, and is suitable for biomedical scaffolds, electronic device substrates and other fields.

2. Super water absorption and water holding capacity

The nanopore absorbs a large amount of water, with a water absorption rate of hundreds of times its own weight, and can lock water for a long time, which is excellent in medical dressings and moisturizing films.

3. Excellent biocompatibility and degradability

Because the structure is natural and pure and the scale is similar to that of the human matrix, bacterial cellulose does not trigger rejection reactions and can gradually degrade into the natural environment or in the body.

4. Excellent thermal stability and barrier properties

High crystallization gives it excellent thermal stability, and the nanonetwork structure has good gas barrier function, making it an ideal choice for food and drug packaging.
