Pickering Emulsions and Hydrophobized Films of Amphiphilic Cellulose Nanofibers Synthesized in Deep Eutectic Solvent AuthorUmair Qasim, Terhi Suopajärvi, Juho Antti Sirviö, Oskar Backman, Chunlin Xu, and Henrikki Liimatainen Year2023 SourceBiomacromolecules LanguageEnglish Pages4113–4122 2917LUMiFugeLFLUMiSizer 12 more LSStability of O/W Emulsions. An analytical centrifugeformation of an O/W interfaceDeep eutectic solvents (DESs) are emerging green chemicals with many appealing features such as high solvent capacitylow vapor pressureand chemical and thermal stability. They can potentially be used to eliminate negative impacts (e.g.toxicity and poor biodegradability) associated with traditional chemical reagents and solvents.1 DESs consist of a mixture of quaternary ammonium or metal salt and a hydrogen bond donor with a melting point significantly lower than that of the individual component.2 DESs derived from organic compounds have intensively been revealed in the valorization and modification of biomaterials.3 Particularlythey provide a sustainable and efficient medium to create functionalized cellulose nanoma- terials for advanced applications. a dual-functioning deep eutectic solvent system based on triethylmethylammonium chloride and imidazole was harnessed as a swelling agent and a reaction medium for the esterification of cellulose with n-octyl succinic anhydride (OSA). The modified or amphiphilic cellulose nanofibers (ACNFs)synthesized using three different OSA-to-anhydroglucose unit molar ratios were further converted into nanofibers with degree of substitution (DS) values of 0.24−0.66. The ACNFs possessed a lateral dimension of 4.24−9.22 nm and displayed surface activity due to the balance of hydrophobic and hydrophilic characteristics. The ACNFs made stable aqueous dispersions; howeverthe instability index of ACNF-3 (0.51) was higher than those of ACNF-1 (0.29) and ACNF-2 (0.33)which was attributed to the high DS-induced hydrophobicitycausing the instability in water. The amphiphilic nature of ACNFs promoted their performance as stabilizers in oil-in-water Pickering emulsions with average droplet sizes of 4.85 μm (ACNF-1) and 5.48 μm (ACNF-2). Self-standing films of ACNFs showed high contact angles for all the tested DS variants eous dispersions of ACNFs were also tested for coating fruits to increase their shelf life. Coatings improved their shelf life by decreasing oxygen contact and moisture loss. More details Edition24, 9 Internal reference2917 Open publication →

Meanwhilethe same procedure was carried out for Composite particles 2. The results are shown in the following Table 2. As can be seen from Table 2in the case of coated Composite particles 2they are coated with a titanate-based compoundand thus show a significantly reduced sedimentation rate as compared to non-coated particles.

The separator includes a semi-crystalline and/or amorphous polymersuch as PVAc and EVAas a binder polymer of an inorganic coat- ing layerwherein the surfaces of the inorganic particles are coated with a coupling agent. Thereforeit is possible to prevent the inorganic particles from being detached from the inorganic coating layer.
