Electrospinning of Bacterial Cellulose Fibres: Challenges for an Innovative Bioengineered Fibre Production Technique

In the last few years, the investigation and findings of alternative and biobased raw material sources has been a focal point of research with respect to reduced impact on the environment.Bacterial cellulose (BC), a biopolymer generated by biosynthesis process, is known for its purity, crystallinity and mechanical properties.Electrospinning of BC has shown potential in various biomedical, packaging and electronic textile-based applications.Ionic liquids (ILs) due to their low vapour pressure and high recyclability have been used in electrospinning of various biopolymers.However, there are few comprehensive studies that investigate the contribution of ILs to electrospinning of BC fibres.This review discusses the potential of using ILs to dissolve BC and its possible effects on the fibre structure, morphology and distribution.It also summarizes the research gaps and challenges available for electrospinning of BC with ILs.Understanding of material properties of BC, the structure of ILs and structure of electro spun fibres is crucial for developing an efficient, eco-friendly and sustainable fibre production process.
