“…Recently, cellulose nanocrystals were also incorporated with water‐soluble thiazoel dyes as a binder, eventually emitting high‐brightness white light if combined with a blue light emitter. [ 149 ] CNC is very cooperative with the other layers, which solves the challenges in integrating metallic wires on flexible LED due to poor adhesion to conventional polymer‐based transparent flexible substrates. What is worth noting is that this phosphorescent device requires operating voltages as low as 7 V and achieves high luminance of up to 43 Cd m −2 (at 50 V).…”

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.

“…A typical ACEL device is composed of two conductive layers and the middle EL layer. The working process is to apply an AC voltage on the conductive layer, whereby the electric field excites the electrons in the EL material, thus exciting the emission center in the EL layer and then the electrons in the excited state transition to emit light [143]. Furthermore, the luminescence spectrum can be regulated by changing the material and AC frequency.…”

With the rapid development of flexible electronic devices (especially flexible LCD/OLED), flexible transparent electrodes (FTEs) with high light transmittance, high electrical conductivity, and excellent stretchability have attracted extensive attention from researchers and businesses. FTEs serve as an important part of display devices (touch screen and display), energy storage devices (solar cells and super capacitors), and wearable medical devices (electronic skin). In this paper, we review the recent progress in the field of FTEs, with special emphasis on metal materials, carbon-based materials, conductive polymers (CPs), and composite materials, which are good alternatives to the traditional commercial transparent electrode (i.e., indium tin oxide, ITO). With respect to production methods, this article provides a detailed discussion on the performance differences and practical applications of different materials. Furthermore, major challenges and future developments of FTEs are also discussed.

“…The upcoming applications make it essential to gain a fundamental understanding of the mechanical properties of CNCs. The experimentally measured tensile strengths and elastic modulus of CNC nanomaterials were reported to be 2–50 GPa and 105–220 GPa, respectively [ 12 , 13 ]. The wide distribution in the reported experimental values stems primarily from differences in uncontrolled measurement conditions and material sources.…”

Cellulose nanocrystals (CNCs) have received a significant amount of attention due to their excellent physiochemical properties. Herein, based on bioinspired layered materials with excellent mechanical properties, a CNCs-graphene layered structure with covalent linkages (C-C bond) is constructed. The mechanical properties are systematically studied by molecular dynamics (MD) simulations in terms of the effects of temperature, strain rate and the covalent bond content. Compared to pristine CNCs, the mechanical performance of the CNCs-graphene layered structure has significantly improved. The elastic modulus of the layered structure decreases with the increase of temperature and increases with the increase of strain rate and covalent bond coverage. The results show that the covalent bonding and van der Waals force interactions at the interfaces play an important role in the interfacial adhesion and load transfer capacity of composite materials. These findings can be useful in further modeling of other graphene-based polymers at the atomic scale, which will be critical for their potential applications as functional materials.
