Method for preparing ionogel fiber based on halogenometallate ionic liquid

Abstract

The present invention provides a method for preparing an ionogel fiber based on a halogenometallate ionic liquid, including the following steps: dissolving a polymer in a good solvent to obtain a polymer solution; or dissolving polymer monomers in a good solvent, and carrying out a polymerization reaction under an action of an initiator to obtain a polymer solution; spinning the polymer solution in a poor solvent to obtain a polymer fiber; and immersing the polymer fiber in the halogenometallate ionic liquid for solvent exchange to obtain the ionogel fiber. The method provided by the present invention enhances the strength, strain, toughness, and energy dissipation under impact of fiber materials through a cyclic stretch-release training assisted by toughening with a halogenometallate ionic liquid, thereby preparing an ionogel fiber with high strength, high toughness, and high energy dissipation rate.
