Bacterial cellulose (BC) is a renewable material that confers high strength and crystallinity, and demonstrates potential to be used as reinforcement in composites. However BC is difficult to process due to its insolubility and low thermal stability. We investigated different methods to treat BC, such as cryo-grinding and sonication, prior to its use with poly-3-hydroxybutyrate (PHB) in fully biodegradable blends by solution and melt blend techniques. In addition, the surface of BC has been modified in situ with PHB (produced by the inclusion of PHB in the medium during BC growth); the aim of this surface modification is to improve the interface between the BC and the matrix PHB and thus the final composite properties.
