“…M and G units can be present in blocks of (M and G) or mixed (MG) [1]. Alginate is water-soluble, being well-known for its gelling capacity [21]. The physicochemical properties of alginate, as well as its gelling ability, are strongly influenced by its structure, which is dependent on the variability in the ratio and sequence of the M and G units.…”

Marine-Derived Polymers in Ionic Liquids: Architectures Development and Biomedical Applications

Marine resources have considerable potential to develop high-value materials for applications in different fields, namely pharmaceutical, environmental, and biomedical. Despite that, the lack of solubility of marine-derived polymers in water and common organic solvents could restrict their applications. In the last years, ionic liquids (ILs) have emerged as platforms able to overcome those drawbacks, opening many routes to enlarge the use of marine-derived polymers as biomaterials, among other applications. From this perspective, ILs can be used as an efficient extraction media for polysaccharides from marine microalgae and wastes (e.g., crab shells, squid, and skeletons) or as solvents to process them in different shapes, such as films, hydrogels, nano/microparticles, and scaffolds. The resulting architectures can be applied in wound repair, bone regeneration, or gene and drug delivery systems. This review is focused on the recent research on the applications of ILs as processing platforms of biomaterials derived from marine polymers.

“…Ionic liquids (ILs) are ionic and non-molecular salts that melt below 100 °C. Normally, they are composed by an organic cation and an organic or inorganic anion, and they are very interesting because of their distinctive properties, such as low vapor pressure, high thermal stability, recyclability, conductivity, and so on [ 22 ]. Due to the low vapor pressure, and good recyclability, ILs have been widely used as green solvents because they do not contribute to the emission of volatile organic compounds (VOCs) to the atmosphere [ 23 ].…”

“…Furthermore, ILs present many molecular interactions that make them powerful solvents for different species, as reported in 2002 by Rogers et al, where they showed very good results dissolving cellulose with 1-Butyl-3-methylimidazolium chloride (BMIMCl) [ 24 ]. BMIMCl interacts with the hydrogen bonds of the cellulose promoting the dissolution of the polysaccharide [ 22 ].…”

Mesoporous Carbons from Polysaccharides and Their Use in Li-O2 Batteries

et al. 2020

Previous studies have demonstrated that the mesoporosity of carbon material obtained by the Starbon® process from starch-formed by amylose and amylopectin can be tuned by controlling this ratio (the higher the amylose, the higher the mesoporosity). This study shows that starch type can also be an important parameter to control this mesoporosity. Carbons with controlled mesoporosity (Vmeso from 0.1–0.7 cm3/g) have been produced by the pre-mixing of different starches using an ionic liquid (IL) followed by a modified Starbon® process. The results show that the use of starch from corn and maize (commercially available Hylon VII with maize, respectively) is the better combination to increase the mesopore volume. Moreover, “low-cost” mesoporous carbons have been obtained by the direct carbonization of the pre-treated starch mixtures with the IL. In all cases, the IL can be recovered and reused, as demonstrated by its recycling up to three times. Furthermore, and as a comparison, chitosan has been also used as a precursor to obtain N-doped mesoporous carbons (5.5 wt% N) with moderate mesoporosity (Vmeso = 0.43 cm3/g). The different mesoporous carbons have been tested as cathode components in Li-O2 batteries and it is shown that a higher carbon mesoporosity, produced from starch precursor, or the N-doping, produced from chitosan precursor, increase the final battery cell performance (specific capacity and cycling).
