Description

technical field

[0001] The invention belongs to the field of functional materials, and in particular relates to a preparation method of a nanocomposite material for absorbing electromagnetic waves. Background technique

[0002] With the rapid development of science and technology and the electronic industry, various digital and high-frequency electronic and electrical equipment radiate a large number of electromagnetic waves of different frequencies into the space during work, resulting in electromagnetic radiation pollution. In order to solve the problem of electromagnetic pollution and realize the stealth of equipment on the battlefield, wave-absorbing materials came into being. An ideal electromagnetic wave absorbing material must meet the requirements of strong absorption, wide bandwidth, light density and thin matching thickness. At present, the microwave absorption properties of traditional electromagnetic wave absorbing materials have been improved, but traditional m...
