“…Previous studies have reported that increasing the BC concentration within the PCL-BC composites lead to an increase in bead occurrence [7]. Furthermore, incorporation of BC into other polymeric materials also resulted in similar outcomes [16,29]. Therefore, the increase in the number of beads in the fibers can be explained by simply the presence of BC.…”

Bacterial Cellulose (BC) has over recent decades shown great versatility in wound healing dressings, but is difficult to spin fibers with at high concentrations. An investigation into the preparation of bandage-like fibrous meshes is carried out to determine the optimal blend of polycaprolactone (PCL) and polylactic acid (PLA) as a suitable carrier for BC. Using a simple centrifugal spinning setup, polymer blends of PCL, PLA and BC are investigated as a ternary system to determine the most suitable composition with a focus on achieving maximal BC concentration. It is found that BC content in the fibers above 10 wt % reduced product yield. By creating blends of PLA-PCL fibers, we can create a more suitable system in terms of yield and mechanical properties. The fibrous samples are examined for yield, fiber morphology using scanning electron microscopy, mechanical properties using tensile testing and chemical characteristics using Fourier-transform infrared spectroscopy. A fibrous scaffold with > 30 wt % BC was produced with enhanced mechanical properties owing to the blending of PLA and PCL.

The production and advanced treatments of bacterial cellulose (BC) and its composites have garnered increased attention in the past decades. As a biodegradable polymer, BC possesses remarkable purity, super-fine nanonetwork structure, biocompatibility, and excellent mechanical properties, which could satisfy the most needs of application areas. The comprehensive knowledge of different BC treatment methods is critical to property modification through composite formation towards multifunctional applications. In this review, we summarised three BC treatment methods and relevant functional composite construction processes, especially the emerging breaking-refactoring methods. It is known that the structure-property-application relationship of BC composites is tightly linked. The successful development of multifunctional BC-based composites will rely on good sustainability and exploration of BC-based composite preparation technology. Applications of BC and its composites based on those treatment methods are reviewed. The properties and characteristics underlying these approaches to BC and its composite applications are also discussed here.
