摘要：In this paper, the effect of nickel-zinc-cobalt ferrite (NZCFO) content on the electromagnetic properties of polymethacrylimide (PMI)/NZCFO was studied. The functional nano-composite was successfully synthesized via novel suspension polymerization. Subsequently, the presence of functional groups and microstructure was investigated by Fourier transform-infrared spectroscopy and scanning electron microscopy, respectively. Based on electromagnetic analysis, it is found that the compressive strength and the entire X-band of the composite foam (thickness greater than 27 mm) reach to 2.6 MPa and an effective bandwidth (R-L < - 10 dB) when the NZCFO content is 30 wt% of the reactive monomer. The analysis confirmed that the PMI/NZCFO (PMI/FO) foam composites enable the loss of an electromagnetic wave through the natural resonance effect of NZCFO. At the same time, the interwoven network structure and the cascade structure have a certain promotion effect on the loss of electromagnetic wave due to porous morphology of PMI foam. The synergetic effect of NZCFO and PMI shows the composite material owes significantly improved electromagnetic and microwave absorption performance.
