Nanjing Tianlu Nano Technology Co., Ltd. Technology Column

In the context of the accelerated integration of new materials and green manufacturing around the world, Bacterial Cellulose BC ，is a nano - scale functional material synthesized by microorganisms. Due to its high purity, high strength and excellent biocompatibility, it is widely used in food, medical, biomaterials and environmental protection fields. Relying on years of experience in nanocellulose research and development and application, Nanjing Tianlu Nano Technology Co., Ltd. is committed to the large-scale preparation and customized development of bacterial cellulose, providing customers in various industries with green and sustainable material solutions.

1. What is bacterial cellulose？

Bacterial cellulose is a natural polymer material synthesized by specific bacteria (such as Gluconacetobacter xylinus ) under specific nutritional conditions . Its basic structure is β-1,4- glucan, the same as plant cellulose, but with higher purity and finer fiber size.

Compared with plant cellulose, bacterial cellulose does not contain lignin and hemicellulose, and has a more regular structure. The diameter is usually between 20 and 100 nanometers, which can form a three-dimensional network-like gel structure , which provides it with natural advantages in biomedical and high-performance membrane materials.

2. Core performance advantages

The developed by Nanjing Tianlu Nano Technology Co., Ltd. bacterial cellulose products have the following significant performances:

1. High purity and biofriendliness

No high-energy demissing process is required to achieve a cellulose purity of >99% , meeting the food and medical grade usage standards. Passed GB and FDA food contact safety specifications.

2. Super hydration capacity and three-dimensional network

Bacterial cellulose forms a three-dimensional porous structure in situ, which can lock water more than 100twice its own weight, and is widely used in moisturizing films, medical dressings, and active material loading platforms.

3. Good mechanical strength and transparency

The dry film has a tensile strength of up to 200 MPa while maintaining good flexibility and transparency. It is a high-quality choice for high-end composite materials and wearable substrates.

4. Easy to functionally modify

The rich surface hydroxyl groups support a variety of chemical modification processes, such as antibacterial, conductive, and temperature-sensitive modification, expanding the possibilities of smart materials and sustainable electronic devices.

3. Comprehensive expansion of application areas

Nanjing Tianlu Nano Technology Co., Ltd. is promoting the industrialization of bacterial cellulose in the following directions:

Application direction	Sample Products
Medical Health	Burn dressings, moist artificial skin, surgical hemostatic membrane, drug guidance platform
