“…This makes them interesting for increasing sustainability in chemical technology. Due their capability to form hydrogen bond networks, DES have demonstrated outstanding ability to interact with polysaccharides [ 22 ] and they are being intensely studied as prospective plasticizers for chitosan [ 50 , 51 , 52 , 53 ], starch [ 54 ] and as media for treatment of chitin [ 55 , 56 , 57 ] or cellulose [ 58 , 59 , 60 , 61 , 62 , 63 , 64 , 65 ]. Additionally, using unsaturated acids such as acrylic or methacrylic acids as hydrogen bond donors [ 66 ] provides DES the ability to polymerize in a new green way for preparation of functional materials [ 67 ].…”

In this work, a novel approach is demonstrated for 3D-printing of bacterial cellulose (BC) reinforced UV-curable ion gels using two-component solvents based on 1-butyl-3-methylimidazolium chloride or choline chloride combined with acrylic acid. Preservation of cellulose’s crystalline and nanofibrous structure is demonstrated using wide-angle X-ray diffraction (WAXD) and atomic force microscopy (AFM). Rheological measurements reveal that cholinium-based systems, in comparison with imidazolium-based ones, are characterised with lower viscosity at low shear rates and improved stability against phase separation at high shear rates. Grafting of poly(acrylic acid) onto the surfaces of cellulose nanofibers during UV-induced polymerization of acrylic acid results in higher elongation at break for choline chloride-based compositions: 175% in comparison with 94% for imidazolium-based systems as well as enhanced mechanical properties in compression mode. As a result, cholinium-based BC ion gels containing acrylic acid can be considered as more suitable for 3D-printing of objects with improved mechanical properties due to increased dispersion stability and filler/matrix interaction.

“…Fan et al extracted CNCs from grape pomace by lactic acid/choline chloride DES. [93] The DES used in this research has a better ability to hydrolyze the cellulose as it has a lower viscosity, due to esterification between the carboxylic acid group of lactic acid and hydroxyl group of choline chloride. Addition of DES on the bleached cellulose at 80 °C for 6 h led to CNCs with a width of 22.0 ± 3.9 nm and a length of 242 ± 45 nm (Figure 4e).…”

202100100polymers, hemicelluloses and lignin, further assembling into cellulose fibers. Cellulose microfibrils are semicrystalline as the tight packing of cellulose chains at the biosynthesis site leads to the formation of crystalline regions which are stabilized by intra-and intermolecular hydrogen bonds as well as dispersion forces. [4] These crystalline regions are periodically separated by very short areas (a few nanometers) where the molecules are disordered but still aligned along the fiber axis. [5,6] These disordered regions are crucial to CNCs preparation and determines the length of resulting CNCs upon chemical treatments. Recent studies suggest such defects are artificially formed during processing, such as drying, rather than inherent to the native microfibril structures. [7,8] CNCs, also known as nanowhiskers, are colloidal rodshaped particles characterized by high crystallinity. [9] They can be extracted from various cellulose sources from plants such as wood pulp, cotton, and ramie, to tunicate and bacteria. [10] Due to their low densities (about 1.6 g cm −3 [11] ) and impressive mechanical strengths (Young's modulus above 100 GPa in the axial direction, similar to that of Kevlar [12,13] ), CNCs have found applications as reinforcement agents in polymer nanocomposites, [14] oxygen and moisture barriers, [14] and for smart coatings in photonic applications, [15] electronic materials, [16] biodegradable packing and food ingredients. [17] The growing interest in such a novel biomaterial has resulted in accelerated industrial production of CNCs, with several companies active in the sector. [18][19][20] As an example, Celluforce is a fully functioning industrial plant in Canada that uses wood pulp as a raw material to produce up to 300 tons of CNCs annually. Melodea Ltd is currently operating a pilot-scale production line that produces sulfated CNCs in Israel (producing 100 kg per day), which, once fully scaled-up, should ultimately be able to produce 200 tons of CNCs per year in Sweden. The University of Maine Process Development Center, based in the US, can produce 90 kg of sulfated CNCs a week from dissolving wood pulp. GranBio (formerly American Process) exploits agricultural residues to produce CNCs using sulfur dioxide/ethanol mixtures with a production capacity of 0.5 ton per day. Blue Goose Biorefineries and Anomera (both in Canada) are producing carboxylated CNCs from viscose grade dissolving pulp with a capacity of about 100-150 kg per week.However, so far, the production of CNCs on an industrial scale mainly relies on sulfuric acid hydrolysis. The first successful preparation of an aqueous colloidal cellulose solution was by Rånby in 1949 using 2.5 N sulfuric acid. [21,22] Since then,

Nowadays, hydrogels as flexible materials have attracted considerable attention in frontier fields such as wearable electronic devices, soft actuators and robotics. However, most hydrogels use water as matrix will inevitably freeze at subzero and damage in severe environment, which greatly reducing their service life and practical value. Herein, nanocomposite hydrogels with self-healing performance at subzero temperatures were proposed by introducing binary water-glycerol continuous phase and dual self-healing interactions. The efficacy of binary solvents was emphasized in preventing formation of ice crystals, enhancing flexible and self-healing abilities of hydrogels in subzero environment. Particularly, linseed oil (LO) as healing agent was effectively loaded in Pickering droplets by cellulose nanocrystals (CNCs). Due to external healing agent and non-covalent bonding, hydrogels showed good self-healing performance at subzero temperature (the healing efficiency could be up to 80.1% for 12 h at -20 ℃). Thus, the designed hydrogels demonstrated multifunctional properties to overcome adverse conditions, which greatly elevated their durability and practicality.
