The application discloses a preparation method of a flexible wave-absorbing resin-based
composite material, which comprises the following steps: mixing a flexible photosensitive resin with multi-walled carbon nanotubes and spherical
carbonyl iron, and performing ultrasonic treatment and mechanical stirring to obtain a flexible wave-absorbing resin-based composite
slurry; and then performing
light curing 3D printing to obtain the flexible wave-absorbing resin-based
composite material. The application further discloses a method for preparing a multi-stage
honeycomb structure flexible wave-absorber for high-frequency application based on the flexible wave-absorbing resin-based
composite material. The preparation method is simple in operation, fast in forming speed and low in cost, and the prepared multi-stage
honeycomb structure flexible wave-absorber has excellent wave-absorbing performance, and even at a high bending angle (150°), the multi-stage
honeycomb structure flexible wave-absorber still has low
reflection loss. In addition, the material has the advantages of high flexible deformation, self-
recovery and no crease damage in repeated bending, greatly improves the environmental adaptability, and can be applied in the fields of intelligent wearable functional devices, intelligent
electronics or intelligent driving and the like.
