Academician Lei Jiang’s Team, University of Science and Technology of China, Interdisciplinary Materials (IF 24.5): Fabrication of Ultra-Strong Polyelectrolyte Nanocomposite Fibers via Microchannel Continuous Spinning

Challenge: High-strength fibers have garnered extensive attention due to their application prospects across various fields. However, the continuous production of polyelectrolyte fibers with ultra-strong mechanical properties remains a significant challenge.
Method: Researcher Chuangqi Zhao from Academician Lei Jiang’s team at the University of Science and Technology of China proposed a microchannel-based continuous spinning (MCS) strategy for preparing polyelectrolyte nanocomposite fibers.
Innovation 1: Nanocomposite fibers were fabricated by incorporating two-dimensional (2D) nanosheets into a negatively charged reaction solution. The resulting fibers, with aligned polymer chains and nanosheets, exhibit outstanding mechanical properties, including a tensile strength of up to 1783.8 ± 47.1 MPa and a modulus of up to 183.5 ± 4.6 GPa.
Innovation 2: Shear-flow-induced orientation of polymer chains, well-aligned nanosheets, and strong interactions within the polymer matrix form a dense and ordered structure, collectively enhancing mechanical performance. Additionally, this method is scalable to various other polyelectrolytes, facilitating the development of high-performance fibers.
