As a new type of carbon material， graphene is considered to have good development prospects in the field of wave absorption due to its excellent properties， such as low density， good conductivity， and large specific surface area. However， owing to poor impedance matching and easy agglomeration of graphene， it is inappropriate to be used as wave absorbent alone. In order to give full play to the performance advantages of grapheme， it is an effective way to compound it with other conductive polymers or magnetic materials， in order to promote its absorbing ability. In addition， the transformation of grapheme from a two-dimensional structure to a three-dimensional porous structure can not only achieve a good absorbing effect， but also makes the material lighter and more flexible， with a lower filling quantity. This paper first discussed the preparation method of three-dimensional graphene materials， and then discussed the research progress of three-dimensional graphene/polyaniline absorbing materials， three-dimensional graphene/polypyrrole absorbing materials， three-dimensional magnetic graphene absorbing materials， and three-dimensional graphene
