Abstract

A composite based on magnetic iron particles and expanded graphite was prepared by thermal combustion and blending methods. Far infrared (8–14 μm) and 8 mm (35 GHz) millimeter wave were selected as attenuation objects. The attenuation performance of magnetic expanded graphite (MEG) composites on infrared/millimeter wave (IR/MMW) was tested by static tests using rubber specimens and dynamic tests by using MEG composites in smoke box. The effects of structure, media material type (carbonyl iron powder and Fe₃O₄) and weight ratio on the IR/MMW attenuation performance of MEG composites were also studied. The experimental results show that the attenuation ratio of MEG composites to IR/MMW in film is 80.3–87.0 %/93.0–99.6 %, respectively. In addition, MEG composites are used as smoke materials for smoke bomb and sprayed into the air to cover a target. As a result, the surface temperature of the target dropped significantly from 79.5 °C to 34.5 °C. The results show that MEG composites have excellent IR and MMW interference capabilities, and can be used as a new material for anti-IR/MMW smoke material.

抗红外/毫米波烟雾材料及其衰减性能研究

通过热燃烧和混合方法制备了一种基于磁性铁颗粒和膨胀石墨的复合材料。选择远红外线（8-14 μm）和 8 毫米（35 GHz）毫米波作为衰减对象。通过使用橡胶试样进行静态测试和在烟雾箱中使用磁性膨胀石墨（MEG）复合材料进行动态测试，测试了磁性膨胀石墨（MEG）复合材料对红外/毫米波（IR/MMW）的衰减性能。此外，还研究了结构、介质材料类型（羰基铁粉和 Fe3O4）和重量比对 MEG 复合材料红外/毫米波衰减性能的影响。实验结果表明，MEG 复合材料对薄膜中红外/毫米波的衰减比分别为 80.3-87.0 %/93.0-99.6 %。此外，MEG 复合材料还可用作烟雾弹的发烟材料，喷射到空气中覆盖目标。结果，目标的表面温度从 79.5 ℃ 显著下降到 34.5 ℃。结果表明，MEG 复合材料具有优异的红外和微波干扰能力，可用作抗红外/微波烟雾材料的新材料。

期刊介绍： The Journal covers the entire field of infrared physics and technology: theory, experiment, application, devices and instrumentation. Infrared'' is defined as covering the near, mid and far infrared (terahertz) regions from 0.75um (750nm) to 1mm (300GHz.) Submissions in the 300GHz to 100GHz region may be accepted at the editors discretion if their content is relevant to shorter wavelengths. Submissions must be primarily concerned with and directly relevant to this spectral region. Its core topics can be summarized as the generation, propagation and detection, of infrared radiation; the associated optics, materials and devices; and its use in all fields of science, industry, engineering and medicine. Infrared techniques occur in many different fields, notably spectroscopy and interferometry; material characterization and processing; atmospheric physics, astronomy and space research. Scientific aspects include lasers, quantum optics, quantum electronics, image processing and semiconductor physics. Some important applications are medical diagnostics and treatment, industrial inspection and environmental monitoring.
