Bacterial cellulose (BC) pellicles consist of a layered structure of planar nanofiber networks, which enables the production of optically transparent composites with an ultralow coefficient of thermal expansion comparable to that of silicon crystal. The BC nanofiber networks suppress crack propagation in the brittle matrix resin, resulting in composites that can be bent without damage (see figure).
