Abstract
Metal organic frameworks (MOFs) derived materials have attracted a lot of attention in the field of electromagnetic wave (EMW) absorption. In this regard, we improved the EMW absorption performance of Ni-based MOF derived materials by introducing sulfur and nitrogen dual-doped graphene (N,S-GS), which possesses good electrical conductivity. The minimum reflection loss (RLmin) of Ni/C/N,S-GS can reach −51.4 dB at 10.1 GHz when the absorber thickness is only 2.43 mm, with an effective absorption bandwidth (EAB) of 3.04 GHz. This work provides us with a novel strategy for the synthesis of composites with high-performance microwave absorption for practical applications.
期刊介绍：
Chemical Physics Letters has an open access mirror journal, Chemical Physics Letters: X, sharing the same aims and scope, editorial team, submission system and rigorous peer review.
Chemical Physics Letters publishes brief reports on molecules, interfaces, condensed phases, nanomaterials and nanostructures, polymers, biomolecular systems, and energy conversion and storage.
Criteria for publication are quality, urgency and impact. Further, experimental results reported in the journal have direct relevance for theory, and theoretical developments or non-routine computations relate directly to experiment. Manuscripts must satisfy these criteria and should not be minor extensions of previous work.
