“…The pros and cons involved with the use of CNMs, a nonconductor, as part of a highly conductive system are well discussed. [267] Various conductive fillers, including silver nanowires (AgNW), [257] LiFePO 4 , [259] MXene, [260] and CNTs, [261,262] have been applied to formulate conductive inks together with CNMs for 3D printing of electronic devices. For instance, AgNW were compounded with CNMs to prepare conductive inks for 3D printing of disposable wireless ion sensors.…”

Rheological Aspects of Cellulose Nanomaterials: Governing Factors and Emerging Applications

of nanomaterials from green, low-cost, abundant, renewable, and biodegradable natural resources. One such attractive bioresource is cellulose, the most abundant biopolymer on earth, which is widely present in various forms of renewable biomass, such as trees, plants, tunicates, and bacteria.Structurally, cellulose is a linear, high molecular weight polysaccharide with repeating glucose units linked by 1-4 glycosidic bonds. Owing to the presence of hydroxyl groups, those linear chains of glucose units link together through van der Waals forces and intermolecular hydrogen bonding to form elementary fibrils, which are further packed into larger aggregates known as microfibrils. [3] Cellulose fibrils consist of disordered (amorphous) regions and highly ordered (crystalline) regions. In the crystalline regions, cellulose chains are closely packed together in highly ordered fashion (parallel to the direction of fibril length), dictated by the intricate intraand intermolecular hydrogen bonding; whereas in the amorphous regions, cellulose chain stacking is less ordered and not as closely packed. Therefore, the amorphous regions are more vulnerable to both physical disintegration and chemical hydrolysis in comparison with crystalline regions. When cellulose is prepared in nano-scale fibrillar or crystalline forms, it is broadly referred to as cellulose nanomaterials (CNMs).The isolation, characterization, modification, and application of CNMs are currently receiving much attention. Understanding Cellulose nanomaterials (CNMs), mainly including nanofibrillated cellulose (NFC) and cellulose nanocrystals (CNCs), have attained enormous interest due to their sustainability, biodegradability, biocompatibility, nanoscale dimensions, large surface area, facile modification of surface chemistry, as well as unique optical, mechanical, and rheological performance. One of the most fascinating properties of CNMs is their aqueous suspension rheology, i.e., CNMs helping create viscous suspensions with the formation of percolation networks and chemical interactions (e.g., van der Waals forces, hydrogen bonding, electrostatic attraction/repulsion, and hydrophobic attraction). Under continuous shearing, CNMs in an aqueous suspension can align along the flow direction, producing shear-thinning behavior. At rest, CNM suspensions regain some of their initial structure immediately, allowing rapid recovery of rheological properties. These unique flow features enable CNMs to serve as rheological modifiers in a wide range of fluid-based applications. Herein, the dependence of the rheology of CNM suspensions on test protocols, CNM inherent properties, suspension environments, and postprocessing is systematically described. A critical overview of the recent progress on fluid applications of CNMs as rheology modifiers in some emerging industrial sectors is presented as well. Future perspectives in the field are outlined to guide further research and development in using CNMs as the next generation rheological modifiers.

“…Due to the proven great potential of the nanocellulosic materials, a deep investigation of their possible applications has also been the subject of an increasing number of articles and patents. If on the one hand they have been tested and efficiently used in small-volume applications, such as medicine or electronics industries (Torvinen et al 2012;Lin and Dufresne 2014;Placket et al 2014;Bacakova et al 2019;Zhang et al 2019), on the other it has been proved that the use in high-volume industries, such as papermaking, is very challenging due to the required high loadings, which has delayed their immediate use. In fact, recent reports have stated that more than twenty thousand tonnes of nanocelluloses are necessary to fulfil the annual needs of the papermaking industry (Miller 2019), while the current industrial facilities for their production generate much less than this.…”

“…The conductive and transparent RCF can be supportive in the manufacturing of flat-panel displays, wearable electric devices and sensors, defrosting windows, etc. (Cao et al 2014;Lee et al 2014;Zhang et al 2019b). More importantly, transparent RCF presents superior flexibility; thus it could be favorable in the foldable and light-weight electronic devices.…”

Regenerated cellulose film (RCF) has potential as a conductive substrate due to features such as its degradability, transparency, and flexibility. Indium doped tin oxide (ITO) is a conventional conductive material, but its rigidity restricts the formation of flexible conductive film. In this study, silver nanowires (AgNWs) were introduced between the RCF and the ITO conductive framework. Additionally, the fabrication of flexible, conductive, and transparent RCF was conducted. The AgNWs-ITO based RCF demonstrated high conductivity (170 Ω per sq) and transparency (78%) by the addition of 50 μL of AgNWs. After bending the sample 50 times with a 5 mm curve radius, the as-prepared conductive RCF presented an electric resistance improvement of 19%, with a 485% increase for the control ITO-based RCF. This is a result of the AgNWs framework, which can lessen the destruction of the bending treatment on the conductive layer and can also desirably connect the ITO conductive sections. The novel approach can expedite the versatile applications of flexibly conductive RCF on printable, portable, and wearable electronic devices.
