With the development of science and technology, the increase of electronic products in the living space, which makes human beings in different degrees of electromagnetic radiation environment, will cause some damage to human tissues, organs and systems. The health hazards and pollution from electromagnetic radiation draws peoples more attention. At present, most of the researches are about the absorption properties of absorbing materials and radar absorbing in the military, while the research on civil use is very few, hardly in the field of indoor absorbing materials and the structure of the wall. It is very urgent to carry out the application in building materials. In this paper, the research status of carbonbased microwave absorbing materials, such as graphite, carbon black, carbon fiber, etc., and its application in building materials are briefly introduced. Finally, the prospectives on indoor absorbing building materials and protective measures of wall structures are discussed.
