Bacterial cellulose (BC) is a natural and environment-friendly polymeric material produced by different microorganisms. It is unbranched and comprised of nanofibrils, made up of β-(1-4) glycosidic linked glucose units. The linear glucan chains in BC form highly regular intra- and inter molecular hydrogen bonds, which stabilize its reticulate structure. BC possesses excellent properties such as soft elastomeric nature, biocompatibility, bioadhesion, swelling capacity, and mass transport, etc. and finds various applications in food, biomedical, and functional energy related fields. Our research group use BC to fabricate a series of functional materials for energy and biomedical application. For instance, BC based electroactive composites are used for energy storage devices, flexible supercapacitors, and energy harvest devices in energy related fields. Meanwhile, BC based bioactive and ordered structured composites are used for skin tissue repair materials, artificial blood vessels, intervertebral disc replacement materials, controlled-release drug carriers, and injectable embolization agents in biomedical engineering field.
