Controllable preparation of nano-cellulose via natural deep eutectic solvents prepared with lactate and choline chloride

Insights into the critical role of anions in nanofibrillation of cellulose in deep eutectic solvents

“…Among them, Cl − competed with hydroxyl groups in cellulose to form hydrogen bonds, resulting in a weakening of strong hydrogen bond interactions in cellulose. Therefore, LA/ChCl DES can depolymerize cellulose by breaking hydrogen bonds in molecular chains under mild conditions (Wu et al 2023). Although few studies have reported that DESs composed of alcohols, urea or amino acids and ChCl were used for the preparation of CNF, but the effect is generally not up to expectations, and it was only applied to the pretreatment of biomass (Tong et al 2023, Suopajärvi, Sirviö and Liimatainen 2017, Smirnov et al 2020).…”

Preparation of hydrogels with self-reinforced mechanical properties using ball-milled microcrystalline cellulose and regenerated cellulose from deep eutectic solvent

“…Wu et al dissolved cellulose from eucalyptus pulp using DES prepared from ChCl and dl -lactic acid (LA) and successfully regenerated cellulose by mechanical sonication. 21 In addition, Dong et al pointed out that cellulose pretreated with acidic DES met the high-value utilization requirements for the production of cellulosic materials. 19 At this stage, cellulose ionogels based on choline chloride-based deep eutectic solvents have excellent environmental stability, electrical conductivity, good biocompatibility, and a wide operating temperature window and are prominently used in the fields of wearable electronic devices, smart artificial skins, and human–computer interaction.…”

Using deep eutectic solvent dissolved low-value cotton linter based efficient magnetic adsorbents for heavy metal removal

“…[36][37][38] To overcome this, a new type of ionic liquid analogue called deep eutectic solvents (DESs) has emerged, which are low-cost, easy to prepare, non-toxic, and biodegradable. [39][40][41] Using DESs to dissolve cellulose can increase its reactive form and facilitate subsequent modications.…”
