随着现代科学技术的发展,电磁波辐射对环境的影响日益增大。在机场,飞机航班曾因电磁波干扰无法起飞而误点;在医院,移动电话常会干扰各种电子诊疗仪器的正常工作;电脑的普及应用,使得电脑病、电磁过敏症频频出现。因此,治理电磁污染,寻找一种能抵挡并削弱电磁波辐射的材料——吸波材料,已成为材料科学的一大课题。吸波材料是能吸收投射到它表面的电磁波能量,并通过材料的损耗变为热能而产生吸收的一类材料。在工程应用上,除要求吸波材料在较宽频带内对电磁波具有高的吸收率外,还要求它具有质量
With the development of modern science and technology, the impact of electromagnetic radiation on the environment is increasing day by day. In the airport, the flight of the aircraft had been unable to take off due to electromagnetic interference and lapsed; in hospitals, mobile phones often interfere with the normal operation of various electronic medical instruments; the popularization and application of computers make the frequent occurrence of computer diseases and electromagnetic allergies. Therefore, to deal with electromagnetic pollution and to find a material that can resist and weaken the radiation of electromagnetic wave - absorbing material has become a major issue in material science. Absorber material is a type of material that absorbs the energy of an electromagnetic wave that is projected onto its surface and that absorbs energy by its loss into heat. In engineering applications, in addition to the requirements of absorbing materials in a wide band of electromagnetic waves with high absorption rate, but also requires it to have the quality
