Zusammenfassung:The increasing electromagnetic pollution due to the widespread use of electronic devices has drawn attention to the development of high-efficiency electromagnetic wave absorption materials. In this study, polypropylene (PP)/Ni composite materials were prepared using the fused deposition modeling method, with PP as the matrix. The mechanical and absorption properties were investigated, showing that the PP-based materials exhibited good mechanical performance with a tensile strength of 25.3 MPa and an elongation at break of 32.1%. At a Ni content of 50% and a thickness of 1.9 mm, the composite material showed absorption properties of −24.31 dB and 5.6 GHz. The absorption bandwidth covered the entire X and Ku bands (6.4–18 GHz) with adjustable thickness ranging from 1.5 to 4 mm. The combination of excellent absorption and mechanical properties makes these materials promising for the fabrication of complex absorber devices.
