Ionic liquids as novel solvents for the dissolution and blending of wool keratin fibers

Isolation and Characterization of Lignin from Rubber Wood in Ionic Liquid Medium

“…Ionic liquids have been hailed as the green alternative to conventional volatile organic solvents (VOSs) in chemistry due to their novel properties, while maintaining the ability to dissolve a wide range of organic and inorganic compounds. Ionic liquids are capable of dissolving complex macromolecules and polymeric materials such as lignocellulose with high efficiency (Liu, et al, 2005;Xie, et al, 2005). Recently, ionic liquids that being considered as green solvents have been successfully used to dissolve and process lignocellulosic materials without derivatization (Wu, et al, 2004).…”

Effect of fibre spinning conditions on the electrical properties of cellulose and carbon nanotube composite fibres spun using ionic liquid as a benign solvent

“…To overcome the first challenge, room temperature ionic liquids such as EMIMAc can be employed as environmentally benign solvent, which is safer and easier to handle than traditionally used solvents such as carbon disulphide [9], sulphuric acid [10] and N-methylmorpholine-N-oxide (NMMO) [11]. A number of researchers have used ionic liquids for fibre stretching/spinning of cellulose [12][13][14][15][16][17][18], wool [19,20], chitin [21][22][23][24] and other natural polymers [25][26][27][28], as well as composite fibres of cellulose [8,29]. Despite this progress, the remaining two challenges, uniform dispersion of carbon nanotube in cellulose solution dope and avoidance of high degree of alignment of carbon nanotubes during fibre spinning, still remain largely unaddressed.…”

Keratinous Materials as Novel Absorbent Systems for Toxic Pollutants

“…Therefore, aqueous solutions of chaotropic reagents such as urea or guanadinium hydrochloride are also needed to bring the bulk of the soluble proteins into solution [18][19][20] . There are reports of ionic liquids being used to solubilize keratin materials through breaking intermolecular disulfide and hydrogen bonds within keratin proteins [21][22][23][24][25] .…”
