Description

technical field

[0001] The invention belongs to the field of preparation of electromagnetic wave absorbing materials, in particular to a carbon nanotube wave absorbing material with magnetic alloy particles loaded on the surface and a preparation method thereof. Background technique

[0002] In modern warfare, stealth technology has become one of the cutting-edge military technologies in the world, and the research and application of radar wave absorbing materials (referred to as absorbing materials) is an important part of the development of stealth technology. In addition, with the development of information technology, various electronic devices are widely used, and electromagnetic wave radiation has become a new social hazard. Electromagnetic Interference (EMI) caused by electromagnetic wave radiation will not only affect the normal operation of various electronic devices, but also be harmful to human health. Absorbing materials can absorb electromagnetic radiation and ...
