Abstract:
This study investigates the biosynthesis of microbial cellulose–electrospun nano-fibrous membrane hybrid nano-fabric via the use of a modified bioreactor. Microbial cellulose is known for its high liquid absorbency and hygienic nature. Electrospun nano-fibrous membranes, on the other hand, exhibit excessive surface hydrophobicity in typical conditions. As such, this research intends to improve the hydrophilic property of electrospun membranes through in situ self-assembly of microbial cellulose nano-fibrils on membrane’s surface. Scanning electron microscopy showed successful growth of microbial cellulose nano-fibrils on the surface and within the structure of electrospun membranes which could possibly contribute toward improved tensile properties. Some functional properties of hybrid nano-fabric, including water absorbency, drying time, and amount of vertical wicking, were determined and compared with pure electrospun membrane samples. Results showed that water absorbency, wicking ability, and drying time increased, as a result of microbial cellulose reinforcement. The average increase in water absorption capability and water-holding time was 72.8 and 32.65%, respectively, whereas wicking ability increased up to 16.5%. In conclusion, the results demonstrate that microbial cellulose contribution has importance for hybrid nano-fabric in terms of key material characteristics that are appropriate for wound dressing and related applications.
