Abstract

ABSTRACT MXene is a new type of transition metal carbon/nitride two-dimensional nanolayered material, which has attracted extensive attention in many fields due to its unique physicochemical properties. Combining MXene with high-performance polymers is expected to obtain nanocomposites with excellent comprehensive properties. In this study, MXene was first modified with acidified 6-aminocaproic acid and then mixed with Polyamide 6 (PA6) matrix. The structure, thermal stability, mechanical properties, and electromagnetic interference shielding efficiency of MXene-based PA6 nanocomposites were studied. The modified MXene was well dispersed in the PA6 matrix with beneficial interfacial adhesion, and the mechanical properties and electromagnetic interference shielding efficiency were significantly enhanced. The method used in this study provides a novel route for fabricating MXene-based polymer nanocomposites with excellent performance. GRAPHICAL ABSTRACT

6-氨基己酸修饰mxene基PA6纳米复合材料的制备及性能研究

MXene是一种新型的过渡金属碳/氮二维纳米层材料，由于其独特的物理化学性质在许多领域引起了广泛的关注。将MXene与高性能聚合物结合，有望获得综合性能优异的纳米复合材料。在本研究中，首先用酸化的6-氨基己酸修饰MXene，然后与聚酰胺6 (PA6)基质混合。研究了mxene基PA6纳米复合材料的结构、热稳定性、力学性能和电磁干扰屏蔽效率。改性后的MXene在PA6基体中分散良好，具有良好的界面附着力，力学性能和电磁干扰屏蔽效率显著提高。该方法为制备性能优异的mxene基聚合物纳米复合材料提供了一条新的途径。图形抽象
