本研究展示了一种简单而经济的策略，通过二价金属离子在氧化石墨烯/聚环氧乙烷（GO/PEO）纳米复合材料中创建强配位键的界面相互作用。强界面相互作用实现了拉伸过程中有效的载荷传递，显著提高了PEO的力学性能。此外，配位键的动态界面相互作用使延伸损失最小化。该策略适用于多种含有配位原子的聚合物基体，从而为制备力学性能显著提高的高性能氧化石墨烯/聚合物纳米复合材料开辟了新的机遇。
A simple and cost-effective strategy to create a strong interfacial interaction of coordination bonds in graphene oxide/poly(ethylene oxide) (GO/PEO) nanocomposites by divalent metal ions are demonstrated in this study. The strong interfacial interaction realizes efficient load transfer during the tensile process to significantly improve the mechanical properties of PEO. In addition, the dynamic interfacial interaction of coordination bonds minimizes the elongation loss. This strategy is applicable to a variety of polymer matrices containing coordination atoms, thus opens up a new opportunity for high-performance GO/polymer nanocomposites with significantly improved mechanical properties.
