“…Expressly, CL-N0 lm has the highest transmittance (87% at 550 nm), this transparency is comparable with that of commercial regenerated lms (Wan et al, 2021). At the same time, the content of NMMO in the coagulation bath have a certain effect on the transparency of the cellulose lm that transmittance of the lm decreased with the increase of the NMMO content in the coagulation bath, which can be explained by the lm formation mechanism of the phase inversion (Ilyas et al, 2021;Cheng et al, 1995;Cheng et al, 1994).…”

The use of nature polymer to prepare degradable films is a sustainable production concept that can improve resource utilization and reduce the environmental pollution caused by traditional packaging waste or another field. Here, a regenerated cellulose film was prepared through the N-methylmorpholine-N-oxide (NMMO) cellulose system. The most critical peculiarity is that films with air barrier and moisture conduction character, because the surface of film is dense and does not allow small molecules like oxygen to pass through, but water molecules can move freely in the film by means of hydrogen bonds. This shows that the cellulose film has in textiles, food preservation, medicine and other fields. Significantly, the film has good tensile strength (maximum strength reaches 149.5 MPa) and light transmittance (more than 80% at 600 nm). Moreover, the effect of coagulation bath concentration, temperature and the content of glycerin on film strength was discussed.

“…Hydrogen bonding is the main interaction of ILs with polysaccharides. Due to the presence of imidazolium C 2 -H, C 4 -H and C 5 -H hydrogen atoms, the hydrogen bonding network between adjacent polysaccharide chains may be disrupted, especially the stronger acidic C 2 -H. Then, cellulose derivatives may be modified, dissolved or partially dissolved by ILs [26,30].…”

Polysaccharides are formed by a long chain of monosaccharides, with the main function of promoting energetic and structural reserves for plants and animals. They can be applied as a base of electrolytes, using ionic liquids (ILs) as a solvent base. The study of electrolytes is an emerging field, as they are applied as secondary batteries, fuel cells, solar cells, supercapacitors and chemical sensors. They operate stably under extreme conditions, maintaining their high thermal stability. Furthermore, their low cost and environmentally safe character, compared to conventional electrolytes, have attracted considerable attention in the scientific field. ILs are composed entirely of ions and could be potentially applied as solvents. As electrolytes, ILs are environmentally friendly, and their use in combination with polysaccharides leads to a synergic effect. In the present study, a systematic review was performed of all papers published from 2014 to 2022 regarding ILs and polysaccharides through a search of three databases. Due to the large number of results found, only papers about electrolytes were considered and the main findings described. This study allows for easy identification of the most relevant fields of study with respect to ILs and polysaccharides, as well as the main gaps to be explored in the literature.

“…After that, they reported a continuous production of cellulose films by extruding cellulose solutions in an extruder. [ 144 ] The influencing factors include the materials, the used solvents, [ 145 ] and the drying process. For the roll to roll process, the relationship of gap size, flow velocity, and film thickness have been demonstrated through experiments and simulations.…”

Cellulose as the most abundant biopolymers on Earth, presents appealing performance in mechanical properties, thermal management, and versatile functionalization. Developing fabrication methods to design functional materials and open new application areas. However, cellulose is hard to be dissolved or melt due to its recalcitrant property. Herein, the recent progress of fabricating cellulose is summarized. First, the unique hierarchical structure of cellulose is fully investigated and the resulted processability is analysed in directions of down to nanocellulose, dissolution, and thermoplastic processing. Then, the reported fabrication methods are summarized in three aspects: (1) self‐assembly from nano/micro cellulose suspensions, especially the formation of cellulose nanocrystals; (2) dissolution–regeneration–drying, covering spinning and solvent infusion processing; and (3) thermoplastic processing, focusing on the setup and the morphology changes of the prepared products. In each aspect, the flowchart of the fabrication method, the mechanism, fabricated products, and effects of processing parameters are explored. Finally, this review provides a perspective on the further direction of fabricating cellulose, especially the challenges toward mass production.
