The invention discloses an MXene composite film flyer and a preparation method thereof, and the preparation method comprises the step of preparing a composite film as a flyer of an exploding foil assembly by taking polyimide with excellent comprehensive performance as a material substrate and taking a flaky MXene material and conductive nanofiber as additives. Through the synergistic effect of the one-dimensional nano material and the two-dimensional nano material, reflection and absorption of electromagnetic waves are achieved, so that the composite film can provide an electromagnetic protection function for the exploding foil assembly while serving as a flyer structural part of the exploding foil assembly. 本发明公开了一种MXene复合薄膜飞片及其制备方法，包括：以具有优异综合性能的聚酰亚胺作为材料基底，以片状的MXene材料和导电纳米纤维作为添加剂，制备成复合薄膜作为爆炸箔组件的飞片。通过一维和二维纳米材料的协同作用，实现对电磁波的反射和吸收，使得复合薄膜作为爆炸箔组件的飞片结构件的同时，还能对组件提供电磁防护功能。
