Current State of Applications of Nanocellulose in Flexible Energy and Electronic Devices

Abstract

Novel and unique applications of nanocellulose are largely driven by the functional attributes governed by its structural and physicochemical features including excellent mechanical properties and biocompatibility. In recent years, thousands of groundbreaking works have helped in the development of targeted functional nanocellulose for conductive, optical, luminescent materials, and other applications. The growing demand for sustainable and renewable materials has led to the rapid development of greener methods for the design and fabrication of high-performance green nanomaterials with multiple features, and consequently new challenges and opportunities. The present review article discusses historical developments, various fabrication and functionalization methods, the current stage, and the prospects of flexible energy and hybrid electronics based on nanocellulose.

Generation of highly amenable cellulose-Iβ via selective delignification of rice straw using a reusable cyclic ether-assisted deep eutectic solvent system

“…The rigidity or incalcitrance of cellulose is usually attributed to the presence of a large number of inter- and intra-molecular hydrogen bonds associated with hydroxyl moieties located in the glycosidic rings 29 . Four different allomorphs (I, II, III and IV) of cellulose have been identified 30 .…”

A Review of Proton Conductivity in Cellulosic Materials

“…Because of its unique structural features and physical properties, nanocellulose is viewed as a potentially useful biopolymer and is actively studied in a wide variety of applications. The incorporation of nanocellulose in composite materials is expected to provide mechanical reinforcement, advanced coatings, sensors, food additives, supercapacitors and batteries, gas separation membranes, medical devices and bioplastics (Guilminot et al, 2007;Hou et al, 2015;Yamasaki et al, 2019;Trache et al, 2020;Dias et al, 2020). Nanocellulose has been enthusiastically embraced in the automotive industry, most clearly demonstrated by the Nanocellulose Vehicle Project in Japan 1 .…”

“…Several recent review papers have been devoted to the application of cellulose and nanocellulose in PEMs, anionexchange membranes, electrocatalyst supports (Vilela et al, 2019), and their broader application in electronic devices (Dias et al, 2020;Trache et al, 2020). Meanwhile, in this review article we focus more specifically on proton conduction in cellulosebased materials, and their application in PEMs and hydrogen fuel cells.…”

Functionalized heterocycle-appended porphyrins: catalysis matters

“…Currently, the research area of materials chemistry has attracted growing interest from scientists in various academic and applied elds since novel advanced materials are aimed to solve the scientic and technological problems in the different spheres of human life. [1][2][3][4][5][6][7][8][9] Among these materials, the most promising are multifunctional hybrid materials, which are characterized by a set of different properties, and thus can be applied in various elds. They can be achieved by the combination of components of diverse origin, for instance, organic and inorganic moieties.…”
