Abstract

The work aims to develop lightweight composite films with superior mechanical properties, heat resistance and electromagnetic shielding performance. In this study, bismaleimide resin (BMI) was used as the resin matrix, while a magnetron-sputtered copper-coated carbon nanotube film (CMF/Cu) was employed as the electromagnetic shielding functional layer. A sandwich-structured BMI/CMF/Cu electromagnetic shielding composite film was prepared through hot-press lamination. The shear strength of the composite film was greater than 10 MPa from 25 ℃ to 225 ℃, and it had a maximum shear strength of 15.11 MPa at 200 ℃, indicating reliable mechanical properties in high-temperature environments. Concurrently, its electromagnetic shielding effectiveness ranged from 42.63 to 48.54 dB within the frequency spectrum of 1-27 GHz. The BMI/CMF/Cu sandwich composite film has been demonstrated to exhibit both excellent mechanical properties and wideband electromagnetic shielding performance. Owing to its unique structural design and superior performance characteristics, this composite film is particularly well-suited for use as an electromagnetic shielding layer in aircraft skins (including airplanes and unmanned aerial vehicles) or as protective enclosures for electronic equipment.
