Bacterial cellulose/graphene oxide (BC/GO) nano‐biocomposites constructed using two methods of in situ and immersion. Scanning electron microscopy showed that a lower amount of GO formed a stronger composite with smaller pores. The in situ method formed a nanostructured composite with an ultrafine particle size distribution. X‐ray diffraction peaks indicated that GO embedded in BC network uniformly. The Young's modulus of the fabricated composites for both methods increased compared to pure BC. DSC analysis showed that the prepared samples were endothermic and in the 350–370°C, the BC/GO sample experienced a 46.9% weight loss. The immersion method formed a composite with higher thermal stability.
