| 目的 制备兼具吸波与耐腐蚀性能的复合材料。方法 使用KH560对羰基铁粉进行改性，在此基础上分别制备羰基铁粉体积分数为0%、15%、20%、25%的复合材料。通过红外光谱(FTIR)、扫描电子显微镜(SEM)、X射线衍射仪(XRD)和矢量网络分析仪(VNA)等测试技术对所制备复合材料的微观特征和电磁性能进行分析对比。研究不同羰基铁(CIP)的体积占比与复合材料电磁波吸收性能和防腐蚀性能之间的关系。结果 通过KH560改性后的羰基铁与环氧树脂混合均匀，形成了紧密的网络结构。羰基铁粉为片状，长度为3~10 μm。当羰基铁粉的体积分数为20%时，样品的吸波性能和防腐性能较好，综合性能相对最佳。所制备的样品在较宽范围内均拥有良好的吸波性能, 在厚度2 mm时反射损耗小于−10 dB的有效带宽达到了4.2 GHz，在8.5 GHz左右时达到了最小反射损耗值(−42.5 dB)。样品在酸和盐的环境下进行7 d加速腐蚀实验后吸波性能未明显降低，这显示了其良好的耐腐蚀特性。结论 将吸波性能优良的羰基铁粉与耐腐蚀性能优异的环氧树脂进行复合，通过调控片状羰基铁粉的体积占比提高了材料的磁导率和介电常数，实现了良好的阻抗匹配，所制备复合材料的吸波性能和耐腐蚀性能均较好。 |

| In order to prepare composites with both microwave absorption and corrosion resistance. KH560 was used to modify the CIPs, composites materials with the volume ratio of modified CIPs of 0%, 15%, 20%, 25% were prepared. FTIR, SEM, XRD, VNA and other modern testing techniques were used to analyze the microscopic characteristics and electromagnetic properties of the prepared composites materials. The relationship between the volume fraction of different CIP and the electromagnetic absorption and corrosion resistance of the composites was studied. When the volume ratio of CIPs was 20%, the microwave absorbing performance and anti-corrosion performance of the sample were better matched, and the overall performance was the best. The composites had good absorption performance in a wide range, as the bandwidth with reflection loss less than −10 dB reached 4.2 GHz at a thickness of about 2.1 mm, and a maximum reflection loss of −42.5 dB at about 2.4 mm. In addition, there was no obvious change for electromagnetic performance in 7 days under acid and salt environment, showing good corrosion resistance. CIPs powder with excellent microwave absorption performance was compounded with epoxy resin with excellent corrosion resistance. By adjusting the volume proportion of flake CIP, the permeability and dielectric constant of the material are improved, and good impedance matching is realized. The prepared composite materials have good microwave absorption performance and corrosion resistance. |
