Microwave absorbing materials including carbon-based materials, conductive polymers, chiral materials and Schiff base materials were reviewed in detail and the future developments of the microwave absorbing materials were prospected. Carbon-based materials such as carbon nanotubes/graphene exhibit excellent microwave absorption property,combining the advantages of carbon materials and nano-materials like good conductivity,light weight,etc. Conductive polymer absorbing materials have potential application in microwave absorbing field for their low density and designability;Chiral absorbing materials with excel-lent absorbing properties such as adjustable chiral parameter and wide absorbing band can obtain directed microwave absorbtion by adjusting chiral parameters;Absorbing properties of Schiff base materials can be significantly enhanced through micro-structure control such as with long-chain conjugated schiff base and its’ salt, or with chirality. Though microwave absorbing materials play an important role in the radar stealth,because of traditional microwave absorbing materials with many drawbacks such as narrow absorp-tion frequency band,low absorption capacity and high density,so that novel microwave absorbing materials have drawn considerable interests in the field of functional materials due to their unique electromagnetic properties.
