제목 Fabrication of Smart Fibers with 2-Dimensional Nanomaterials
초록 In this talk, first, I will introduce a strategy to reconstruct 2-dimensional(2D) nanomaterials into functional materials via wet-spinning. Graphene oxide(GO) sheets can be assembled into 1-dimensional(1D) fibers through a large-scale wet-spinning. Our simple and continuous spinning is beneficial to fabricate high electroconductivity, flexibility, and mechanical strength fibers. Second, by incorporating CNTs inside of graphene fibers, high torsional strength fibers can be prepared. Rheological control to form hybrid fibers with highly oriented inner structures can direct the structural manipulation. Finally, to conclude, our wet-spinning strategy can be applied to other 2D materials. By taking advantage of strong molecular interactions between MXene sheets, mechanically strong fibers can be fabricated by drawing the MXene gel. Due to its defect-free structure, Ti3C2Tx MXene fiber has dense lamella and a highly aligned multiscale structure.
