Bacterial nanocellulose (BNC) is an interesting and extraordinary biopolymer with a huge range of potential technical and biomedical applications. By means of intensive investigations of scale up processes, it becomes necessary to associate the unique properties of BNC and its composites with technical requirements. In this context a great advantage of the BNC synthesis is the in situ formability. Additionally, inorganic and organic additives can be added during the formation of BNC to create a composite. In this study, the influences of various additives including metal-oxide nanoparticles and glucose derivatives on the resulting structure and properties of BNC composites have been investigated by means of the examination of the nanostructure and resulting composition via SEM / EDX, XRD, Raman- and FT-IR spectroscopy. Furthermore, the mechanical properties under typical stresses such as compressive, tensile and cyclic loading conditions were determined.
