Published: Jan. 26, 2021

Self-assembly of two-dimensional MXene sheets is used in various fields to create multiscale structures due their electrical, mechanical, and chemical properties. In principle, nanosheets are assembled by molecular interactions, including hydrogen bonds, electrostatic van der Waals forces. This study describes how colloid can form self-supporting hydrogels. Three-dimensional network gels strengthened reinforced interactions between nanosheets. Stable gel networks beneficial for fabricating highly aligned fibers because endure structural deformation. During wet spinning concentrated colloids a coagulation bath, be transformed into perfectly under mechanical drawing force. Oriented exhibit 1.5-fold increase electrical conductivity (12 504 S cm–1) Young's modulus (122 GPa) compared with other fibers. The oriented expected have widespread applications, wiring signal transmission.
