Abstract

Flexible electromagnetic shielding films have attracted wide attention due to their excellent electromagnetic shielding performance and flexible compact nature. In this paper, a composite film was prepared by combining two-dimensional (2D) transition metal carbonitrides (MXene) with silver nanowires (AgNWs). The AgNWs-induced surface wrinkles of MXene played a dominate role in enhancing its electromagnetic wave absorption properties. Significantly, as-fabricated composite film exhibited electromagnetic shielding performance of up to 60 dB in the X-band (8-12 GHz), where a 70 % increase in absorption of electromagnetic waves was realized compared with the pure MXene films. Additionally, the composite film demonstrated strong mechanical stability with the electromagnetic shielding efficiency remained at 99.65 % even after several hundred bending cycles.
