Description

technical field

[0001] The invention provides a preparation method of macroporous thin-layer carbon using ammonium nitrate assisted, and belongs to the field of novel carbon material preparation. Background technique

[0002] With the rapid development of electronic information technology, the application of electromagnetic waves is becoming more and more extensive. The electromagnetic waves flooded in the environment will not only interfere with the electromagnetic control system and cause equipment failure, but also damage the physical and mental health of human beings. Therefore, it is of great significance to develop absorbing materials with electromagnetic wave absorbing ability. In addition, the application value in military stealth technology has also greatly promoted the research on absorbing materials.

[0003] Because carbon materials have the advantages of excellent dielectric properties, good composite properties, special microstructure, low specific gravity, s...
