Nanopaper Electronics

In the past few years, nanocellulose, as a new‐emerging colloid, has developed into a large family and gained increasing attention owing to its favorable properties. It represents a ubiquitous feature in electronics as different components according to principles extend across energy, lighting management, and transistors and biosensors to information technologies. Within these decades, there are a lot of remarkable phenomena, effects, and performances relevant to a few additional attributes of nanocellulose, making the electronics perform better and better. Toward the rapid nanotechnology development and the need of the society, characterizing this important nanomaterial and making more and more new electronics have become important things to be done. This review consolidates the contribution of nanocellulose to nano‐related electronics, summarizes these methods to utilize nanocellulose as any component in devices, and points out the attributes of the nanocellulose. In the devices, the recent advances into solid‐state electronics, optoelectronic devices, and flexible/wearable electronics are categorized. The intrinsic electrical, dielectric and electronic structures, and properties of nanocellulose related to the device performances are particularly summarized and analyzed, which is believed beneficial in providing a judgment criterion for devices in the future. This is a critical review based on one of the new merging nanoparticles, nanocellulose, which appears unique compared to others, such as carbon nanotubes, graphene, boron nitride, etc. This review summarizes the recent advances in nanopaper electronics related to nanoeffects and new phenomena and relevant properties that are very important to contribute to the performance of new devices.
