Covalent Bonds Reinforced Strength and Modulus of Heterocyclic Aramid Fiber by Interfacial Aminated‐MXene Nanosheets

Advanced Science, EarlyView.
We demonstrate the covalent bonds strategy to enhance the mechanical property of PBIA fiber by using interfacial MXene‐NH2 nanosheets. The MXene‐NH2 nanosheets with reactive amino sites that can serve as nucleating agents and chain anchors to enhance orientation, crystallinity and interchain interaction of PBIA fiber via strong interfacial amido ...
