摘要/Abstract

摘要：

采用电磁波吸收材料来降低电磁波对设备的干扰及对人体的伤害，是目前常用的电磁波防护手段之一。特定结构碳化硅晶须作为一种一维介电材料，其优于普通的晶须、块状和颗粒状的吸波性能引起了研究人员的关注。本研究以生竹粉、硅粉和二氧化硅为原料，通过碳热还原法在不同温度下制备了竹节状碳化硅晶须，并对其结构和吸波性能进行了检测分析。结果表明：以1400℃烧结的竹节状晶须制备的试样在厚度为3 mm，频率为9.1 GHz时，最小反射损耗达到-14.4 dB，有效吸收带宽为1.8 GHz，吸波性能最好，具有进一步研究价值。

Abstract:

The use of electromagnetic wave absorbing materials to reduce the interference of electromagnetic waves on equipment and harm to the human body is one of the currently used electromagnetic wave protection methods. As a one-dimensional dielectric material, silicon carbide whiskers with specific structure have better absorption performance than ordinary whiskers, bulk materials and particle materials. It has become a hot topic in this area. In this study, bamboo-like silicon carbide whiskers were prepared from bamboo powder, silicon powder and silica by carbothermal reduction at different temperatures, then the structure and absorbing properties of bamboo-like whiskers were tested and analyzed. The sintered bamboo-shaped whiskers at 1400℃ have a minimum reflection loss of -14.4 dB and an effective absorption bandwidth of 1.8 GHz at a thickness of 3 mm and a frequency of 9.1 GHz. Its absorbing performance is the best and has further research value.
