In the research and development of high-performance functional materials, ' structural -performance coupling ' is one of the core research logic. Bacterial Cellulose ( BC ), as a microbial-derived nanomaterial, is its naturally generated three-dimensional nanofiber network structure . This structure gives bacterial cellulose extremely strong hydration ability, high moisturizing and stability , providing a solid foundation for its application in many fields such as medical dressings, tissue engineering, hydrogels, environmental adsorption, and skin care products .
Nanjing Tianlu Nano Technology Co., Ltd. has long been committed to the preparation and application technology development of bacterial cellulose materials, and has successfully built a variety of application solutions based on three-dimensional structures and formed a product system that can be industrially exported.
The hydration characteristics of bacterial cellulose come from its unique ' nano-size + porous network + hydrophilic surface ' triple structural characteristics:
Bacterial cellulose is composed of interlaced filaments with a diameter of 20~100 nanometers, which is one order of magnitude thinner than plant cellulose, forming a highly open pore structure that can absorb and lock in large amounts of free and bound water.
The self-assembled spatial network formed during fermentation can not only absorb moisture, but also maintain good mechanical strength, keep the structure intact and not collapse, and support repeated absorption and dehydration cycles.
A large number of hydroxyl groups on the surface of the cellulose form hydrogen bonds with water molecules, making them still viscoelastic in the water absorbing state, which is suitable for stable performance requirements in high humidity environments.
Nanjing Tianlu's actual test data shows that the company's standard-grade bacterial cellulose gel has the following typical water absorption and storage capabilities under static culture conditions:
Performance metrics | Parameter range | Test Method |
Water content | 95%–99% | Gravity method ( GB/T 5009.3) |
Water absorption ratio (dry weight meter) | 100–250 times | Free water absorption method |
Water retention rate ( 48 hours) | >85% | Constant temperature and humidity chamber test |
Rehydration capacity | >90% recovery rate | Freeze-drying and soaking |
This hydration capacity is far beyond that of commonly used moisturizing substrates such as sodium alginate and carbomer. It is an ideal long-term moisture carrier and moisture-control platform material.。
The three-dimensional nanonetwork of bacterial cellulose is not only a structural support, but also highly designable, and can derive a variety of functional applications:
The mesh structure can continuously release moisture , maintain a wet environment in the wound, and help tissue repair and cell proliferation. Adding silver ions, chitosan, etc. can form an antibacterial hydrogel.
The three-dimensional fiber network provides a good loading platform for conductive polymers (such as PEDOT:PSS ) and carbon nanomaterials, improving the mechanical stability and response speed of flexible electrons.
The high hydration ability and breathability make it possible to act as a natural, non-irritating patching cloth in mask applications , and the diffusion effect of carrier actives is better than that of traditional non-woven fabrics or seaweed membranes.
The three-dimensional channel can adjust the release rate and is suitable for adhering to a variety of hydrophilic or hydrophobic drug molecules. It is used for ophthalmic pastes, wound patches, implanted drug-loading membranes, etc.
The high specific surface area and pore volume can adsorb heavy metals, dyes and other pollutants, and are also degradable, making it an ideal substrate for new green adsorbents.
Relying on the optimization and structural control process of independent fermentation bacterial species, Nanjing Tianlu Nano Technology Co., Ltd. can stably provide the following types of three-dimensional network bacterial cellulose materials :
Product Form | Application example | Customizable parameters |
Hydrogel membrane | Medical dressings, cosmetic film cloth | Moisture content, thickness, pore size distribution |
Porous dry film | Covering materials, composite films | Dry heavy density, rehydration capacity |
Functional composite membrane | Antibacterial membrane, sensing base membrane | Carrier ratio, reactive sites |
All products can provide material inspection reports, FDA/GB compliance support, and packaging shaping services according to customer needs to help customers quickly realize productization.
The super hydration capacity and three-dimensional network structure of bacterial cellulose are not only a natural gift from the material itself, but also a new boundary for the continuous expansion of modern biomaterial engineering technology. Nanjing Tianlu Nano Technology Co., Ltd. will continue to deepen material design and structural optimization, create smarter, high-performance and green bacterial cellulose materials, and provide a new generation of basic material solutions for the biomedical, new energy and environmental protection industries.
