Structure and properties of polypyrrole/bacterial cellulose nanocomposites

► Conducting nanocomposites based on bacterial cellulose/polypyrrole were obtained. ► The composites were prepared using ammonium persulfate or iron III hydrochloride. ► The morphology of composites prepared with two types of oxidant is different. ► The properties of composites were influenced by the oxidant used in the reaction.
