Takada A, Kadokawa J - Biomolecules (2015)

Bottom Line: The resulting ion gels have been characterized by suitable analytical measurements.Characterization of a pregel state by viscoelastic measurement provided the molecular weight information.Furthermore, the polysaccharide ion gels have been converted into value-added sustainable materials by appropriate procedures, such as exchange with other disperse media and regeneration.

ABSTRACT
A review of the fabrication of polysaccharide ion gels with ionic liquids is presented. From various polysaccharides, the corresponding ion gels were fabricated through the dissolution with ionic liquids. As ionic liquids, in the most cases, 1-butyl-3-methylimidazolium chloride has been used, whereas 1-allyl-3methylimidazolium acetate was specifically used for chitin. The resulting ion gels have been characterized by suitable analytical measurements. Characterization of a pregel state by viscoelastic measurement provided the molecular weight information. Furthermore, the polysaccharide ion gels have been converted into value-added sustainable materials by appropriate procedures, such as exchange with other disperse media and regeneration.

biomolecules-05-00244-f003: Schematic diagram for procedures of fabrication of polysaccharide ion gels with IL and conversion into value-added sustainable materials.

Mentions: In recent years, we have extensively used ILs as disperse media in polysaccharide-based gels, so-called “ion gels”, which include ILs in the polysaccharide network matrixes (Figure 3) [24,25,26], besides the traditional use as solvents mentioned above, it was found that cellulose formed an ion gel with BMIMCl [27]. Furthermore, the conversion of the ion gels of various polysaccharides into value-added sustainable materials has also been performed by suitable treatments, such as exchange of disperse media and regeneration (Figure 3) [28,29,30]. In this article, we presented a review of these studies with sections separated in accordance with the kinds of polysaccharides.
