摘要： Disclosed are methods for preparing a lignin/poly(vinyl alcohol) (PVA) fiber and for preparing a lignin/polyacrylonitrile (PAN) fiber. The methods can comprise adding a dope of lignin and PVA or a dope of lignin and PAN to a coagulation bath containing a solvent comprising one or more components, wherein the one or more components are present in the solvent in concentrations based on the hydrogen bonding character (fH) of the solvent, the polar character (fP) of the solvent, and the dispersive character (fD) of the solvent; and gel-spinning a lignin/PVA fiber or a lignin/PAN fiber from the coagulation bath.

摘要： Compositions that include a polymer and an aldaric acid, such as glucaric acid, are disclosed. The compositions may include polyvinyl alcohol and glucaric acid. The compositions may also include polyacrylonitrile and glucaric acid. In addition, the compositions may further include lignin. Also disclosed are fibers including the compositions, methods of making the fibers, and uses of the fibers.
