Nowadays, with the dramatic development of microwave absorbing materials (MAMs), broadband and lightweight are still a topic that cannot be bypassed. Considering the drawbacks of single-component materials and the necessity of magnetic–electric synergistic effect. A novel porous carbon-based aerogel composite with a three-dimensional (3D) biological template is prepared by using rational impedance matching design and multifunctional optimization. Specifically, the coupling of porous materials as well as the synergy of multilevel carbon materials. A novel aerogel of NiCo layered double hydroxide (LDH)/C@Diatomite (De) was prepared by thermal carbonization to convert polypyrrole (PPy) into C particles deposited on the surface of magnetic LDH, coupled to form an aerogel on the basis of De carrier. The influence of the involvement of multilevel carbon on the electromagnetic wave absorption (EMWA) properties of the composites and its potential attenuation mechanism as well as the synergistic effect of the coupling of porous materials are revealed. As a result, the effective absorption bandwidth (EAB) is 8.56 GHz with a reflection loss minimum (RLmin) of −46.85 dB at a thickness of 2.7 mm. With super hydrophobicity and thermal management properties. This work not only provides inspiration for the development of new aerogel MAMs with superior performance, but also has great potential for further development and practical application.
