Carbon nanotubes are the promising microwave absorbing agents, served as a potential stealth materi鄄
als, electromagnetic shielding materials or absorbing materials using anechoic chamber. The recent research achieve鄄
ments and the problems concerning electroless plating modification of carbon nanotubes and polymer blend with carbon
nanotubes and hybrid carbon nanotubes with ferromagnetic material are reviewed. Finally,some suggestions for the de鄄
velopment of carbon nanotubes used as a absorbing material are put forward.
