Nanopaper is a kind of film which is made up of nanocellulose fibers. Featuring high transparency and low roughness, nanopaper is considered an ideal substrate for flexible electronics. Compared with synthetic polymers, nanopaper is decomposable and provides a promising candidate for the fabrication of green electronics. In this review, fabrication of nanopaper, its properties and applications in field effect transistors, energy devices and OLEDs are summarized. At last, challenges to nanopaper including large-scale and low-cost fabrication and application in green electronics are addressed. The potential application of nanopaper in biosensors is also discussed.
