Nanopaper Electronics

Abstract

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.

Perovskite quantum dots embedded paper photodetectors with high flexibility and self-powered operation

“…The paper-based flexible optoelectronics have drawn significant attention recently because of the extended market demand for wearable and foldable consumer electronics. 39 To verify the application of the MQDs/CNF hybrid paper in flexible electronics, a bending test was performed to examine whether it could reliably function under bent conditions. As depicted in Fig.…”

Utilizing the synergistic effect between the Schottky barrier and field redistribution to achieve high-density, low-consumption, cellulose-based flexible dielectric films for next-generation green energy storage capacitors

“…1–14 After realizing the harmful effects of petroleum-based materials on the environment and human health, especially during their degradation process, in recent years, polymer-based dielectric materials have changed from biaxially oriented polypropylene (BOPP)-based, polyvinylidene fluoride (PVDF)-based, and polyimide (PI)-based systems to candidates exhibiting partial/complete biodegradability. 15–18 Among them, cellulose is the most commonly used material, not only as it is the most abundant natural polymer on the earth but also for its intrinsic spontaneous polarization and good voltage endurance. The latter two properties can be further elaborated as follows: (1) the polarization of cellulose originates from three different hydroxyl groups, which form both the inter- and intramolecular hydrogen bonds in their polymeric chains as shown in Fig.…”

Broadband paper-photodetectors for visible & UV light detection

“…To comply with these demands, various materials are being explored including organic materials, 8 low-dimensional materials [9][10][11][12][13] and natural materials 14,15 alongside traditional silicon or inorganic semiconductor-based ones. [16][17][18] Among them, paper or cellulose paper has been widely utilized as a substrate for various paper-based electronics [19][20][21] and sensors. [22][23][24][25][26][27][28] Due to the inherent bio-friendly, eco-friendly, porous, flexible, and scalable nature of cellulose papers, numerous paperbased sensors have been developed and extensively discussed in various review articles.…”
