Bacterial Cellulose Hydrogel

Bacterial Cellulose Hydrogel is a high-purity, water-rich nanofibrous material engineered for versatile applications across healthcare, personal care, advanced materials, and sustainable product development. Composed entirely of cellulose, it features an interconnected network of nanoscale fibres, abundant hydroxyl groups, and a water content exceeding 95%. Its tunable thickness and adaptable mechanical and rheological properties make it a promising platform for developing next-generation material formats.

Key Features & Properties

• High Water Content: More than 95% water, providing a hydrated, hydrogel-like structure.
• High Purity: Composed of cellulose, a polymer of repeating glucose units rich in hydroxyl functional groups.
• Tunable Thickness: Customizable from a few micrometres to several millimetres.
• Nanofibrous Architecture: Initial hydrogel nanofibres typically range from 20–60 nm in diameter, with larger apparent fibre dimensions possible at greater thicknesses due to aggregation.
• Mechanical Flexibility: Can withstand tensile strains of up to 30%.
• Adaptable Flow Behaviour: Thin films can undergo plastic deformation. The rheological flow point varies from approximately 0.5 to 20 Pa, depending on thickness.
• Thermal Stability: Reported to remain stable at temperatures up to 200°C under the conditions evaluated.

Designed for Diverse Applications

Its high water content, nanoscale fibrous network, functional hydroxyl groups, and tunable physical properties offer opportunities for applications in wound care, tissue engineering, active-ingredient delivery, personal care formulations, and functional material development.

Dried Sheets & Composites

Engineered Porosity. Customizable Structure. Versatile Performance.

Bacterial Cellulose Dried Sheets are lightweight, cellulose-based materials whose density, porosity, and rehydration behaviour can be tailored through controlled drying methods. Depending on the drying process, the sheets can be engineered as dense, compact structures or highly porous, reswellable networks, enabling versatility across healthcare, personal care, packaging, filtration, and advanced material applications.

Key Features & Properties

• Customizable Microstructure: Sheet density and porosity can be tailored by selecting the appropriate drying method.
• Oven-Dried Sheets: Form dense, compact structures with reduced porosity.
• Freeze-Dried Sheets: Retain a highly porous network with the ability to reabsorb water and reswell.
• Cellulose-Based Composition: Derived from bacterial cellulose, with a nanofibrous architecture and abundant hydroxyl functional groups.
• Application-Driven Design: Drying conditions can be selected to achieve the desired balance of compactness, porosity, and rehydration performance.

Potential Applications

Suitable for exploring applications in wound-care materials, absorbent products, active-ingredient delivery, filtration, sustainable packaging, and functional cellulose-based composites.
