“…[131] Copyright © 2019 Wiley Periodicals, Inc.). The characteristics of the final hydrogel are related to the regeneration technique and composition of the regeneration bath [132]. The density of the regenerated cellulose hydrogel depends on the type of antisolvent that determines the mixing rate between the IL and the antisolvent during the regeneration process [104] (Figure 4A).…”

This review summarizes the recent advances in preparing cellulose hydrogels via ionic liquid-based processes and the applications of regenerated cellulose hydrogels/iongels in electrochemical materials, separation membranes, and 3D printing bioinks. Cellulose is the most abundant natural polymer, which has attracted great attention due to the demand for eco-friendly and sustainable materials. The sustainability of cellulose products also depends on the selection of the dissolution solvent. The current state of knowledge in cellulose preparation, performed by directly dissolving in ionic liquids and then regenerating in antisolvents, as described in this review, provides innovative ideas from the new findings presented in recent research papers and with the perspective of the current challenges.

“…26,27 Likewise, due to their low volatility and nonflammability, ILs have also been used as environmentally friendly solvents in many chemical reactions as substitutes for traditional organic solvents. [28][29][30][31][32][33] They are designated as green solvents because they do not pollute air and can be easily recovered and recycled. Although they may not be toxic to human cells, recent studies have shown the toxicity of these ILs towards microorganisms.…”

“…OCC is approximately 75% cheaper than BKP, and since the use of delivery packaging is increasing attributable to covid-19, recyclable OCC is being evaluated as a feedstock for eco-friendly materials (Ruamsook et al 2015;Copenhaver et al 2021). However, the industry applications in which OCC can be used is limited and it is typically re-used as a raw material for cardboard boxes, because OCC fibers tend to become stiff and rigid through repeated recycling processes known as "hornification" which leads to decreased strength properties of the OCC pulp (Diniz et al 2004;Lin et al 2020;Sangtarashani et al 2020). BKP, UKP, and OCC are good feedstock sources for manufacturing cellulose nanofibrils (CNFs) via mechanical treatment (Yousefhashemi et al 2019;Kargupta et al 2021).…”

Three types of wood pulp feedstocks were disk refined to produce cellulose nanofibrils at different fineness levels ranging from 50 to 100%, and the resulting aqueous suspensions of cellulose nanofibrils were spray dried. The spray drying experiments were carried out to examine different processing conditions for the different CNF feedstock types and fines level at various suspension concentrations to produce dry samples with free-flowing powder morphologies. The fineness levels and solids contents of CNF suspensions were set to 80% or more and 1.8% or less, respectively. If the solids content of the CNF solutions was high and the fibrillation level was low, plugging was experienced in the spray head because of the high viscosity of the suspensions, resulting in production of poor-quality powders. In terms of energy savings, even if the CNF suspension solids content was increased to 1.5 wt.%, the powder quality and the production yields were excellent. It was confirmed that high-quality powder under 20 µm were produced at a 90% fibrillation level of all CNF feedstocks. The resulting dry CNF powders were characterized to determine particle size distributions and morphological properties via a scanning electron microscope and a laser diffraction particle size analyzer. The particle sizes were smaller at higher fibrillation levels and lower solids content of the CNF suspensions. CNF suspension derived from bleached kraft pulp, the average particle size decreased by 43% and 33% with the lowered solids contents from 1.8–1%, and the increased fineness levels from 80–100%, respectively.
