Stable broadband microwave absorption is widely interested for their irreplaceable role in stealth technology for multiband microwave communication and detection. In this paper, a flexible broadband microwave absorber with self-recoverability was fabricated by self-assembling graphene sheets into polypropylene 3D framework. The as-fabricated absorber has a full-band absorption (more than 90%) in the working ranges of microwave communication and detection in military radars (2-40 GHz and 75 -110 GHz), exhibiting larger bandwidth than the absorbers reported in literature. Furthermore, its bandwidth with more than 97% absorption (Reflection loss
