“…It is interesting to note that for the cellulose nanocrystals in DES, an almost complete recovery of viscosity values was observed, which suggests that in the case of nanofibers, the process of their reverse relaxation to a tangled state is significantly more inhibited compared to nanocrystals [ 39 ]. This result is probably due to the lower mobility of BC nanofibers in dispersion compared to nanocrystals, due to the cooperative effect of the formation of hydrogen bonds by objects with a high aspect ratio.…”

“…The possibility of ILs and their new analogs—deep eutectic solvents (DES)—to be solvents or dispersive media for natural polymers is often emphasized. This property is used for polysaccharide processing [ 37 , 38 ], for the preparation of self-healable ion conducting hydrogels [ 39 , 40 , 41 ], and in the 3D printing of sensors [ 42 ]. Cellulose, as the most abundant polymer, is often used in such materials [ 43 ].…”

Two polymerizable ionic liquids (or monomeric ionic liquids, mILs) namely 1-butyl-3-methylimidazolium and choline acrylates ([C4mim]A and ChA, respectively) were synthesized using the modified Fukumoto method from corresponding chlorides. The chemical structure of the prepared mILs was confirmed with FTIR and NMR study. Investigation of the thermal properties with DSC demonstrates that both mILs have a Tg temperature of about 180 K and a melting point around 310 K. It was shown that the temperature dependence of FTIR confirm the Tg to be below 200. Both mILs exhibited non-Newtonian shear thinning rheological behavior at shear rates >4 s−1. It was shown that [C4mim]A is able to dissolve bacterial cellulose (BC) leading to a decrease in its degree of polymerization and recrystallisation upon regeneration with water; although in the ChA, the crystalline structure and nanofibrous morphology of BC was preserved. It was demonstrated that the thixotropic and rheological properties of cellulose dispersion in ChA at room temperature makes this system a prospective ink for 3D printing with subsequent UV-curing. The 3D printed filaments based on ChA, containing 2 wt% of BC, and 1% of N,N′-methylenebisacrylamide after radical polymerization induced with 1% 2-hydroxy-2-methylpropiophenone, demonstrated Young’s modulus 7.1 ± 1.0 MPa with 1.2 ± 0.1 MPa and 40 ± 5% of strength and ultimate elongation, respectively.

“…However, DESs generally showed poorer solubility than ILs since the low order of DESs could not supply sufficient entropy gain of the solvent to drive the dissolution. [73,74] Therefore, developing new and more efficient DESs for cellulose dissolution is still required.…”

Cellulose‐based conductive gels are representative nanomaterials and have a good flexibility, biodegradability, and biocompatibility due to the cellulose. Therefore, they are considered as important candidates for the development of next generation nanoarchitectonics materials for electronics and green energy. To date, conductive cellulose gels have been widely investigated for various applications, including sensors, energy storage devices, energy generators, and actuators. A number of studies has shown that cellulose‐based conductive gels have a superior performance compared to gels prepared using petroleum‐derived chemicals. Therefore, in this review, we will introduce the general preparation method of cellulose‐based conductive gels in order to present the latest research results and to provide information for future nanoscience and research studies. Also, the main applications of cellulose‐based conductive gels and the progress of their research will be described.

“…hydrolyze the amorphous region of cellulose and subsequently release CNCs after the DES treatment. Vorobiov et al (2022) studied two types of CNCs: CNCs prepared by DES, and CNCs prepared by acid hydrolysis, as well as their influence on 3D printing (rheological behavior of dispersions). Microcrystalline cellulose with an average particle size of 50 µm was used as the raw material.…”

In recent years, the demand for environment-friendly products has been on an increasing trend among researchers and industry for sustainable development. Deep eutectic solvents are green solvents which, due to their properties (biodegradability, recyclability, low cost, availability, easy preparation, low toxicity, chemical and thermal stability), can be used in various fields such as polymer chemistry, which includes nanocellulose isolation and polysaccharides processing. Several studies have illustrated the effectiveness of using deep eutectic solvents instead of the conventional reaction system to produce and disperse nanomaterials. This work summarizes the use of deep eutectic solvents in the isolation of cellulosic nanomaterials from different types of biomass. Deep eutectic solvents demonstrate high effectiveness in swelling lignocellulosic biomass and producing cellulose nanomaterials. Overall, deep eutectics solvents represent an innovative and effective pretreatment process for the fractionation of raw cellulose-containing fibres to promote subsequent isolation of nanomaterials made from cellulose.
