关键字：CoFeAl-LDH GO in-situ grow Microwave absorption
摘要：Hydrotalcite-like CoFeAl-layered double hydroxide sheets (CoFeAl-LDH) are employed to construct the CoFeAl-LDH/G hybrids via the sufficient metal ions absorption and subsequent in-situ growth on graphene oxide (GO) surfaces. The uniform integration not only retains the inherent excellent properties of GO, but also overcomes some weakness like shallow skin depth and severe layers restack. In addition, extra dipolar polarization (induced by donated electron from GO) and Maxwell-Wagner-Sillars (MWS) effect (caused by abundant charges accumulation at the interfaces) also contribute to the remarkable microwave absorption performance. The maximum RL value and the effective bandwidth reach -23.8267 dB and 7.36 GHz, respectively at 2.5 mm. Consequently, study of structure-performance relationship is meaningful for the design and fabrication of binary absorbers with effective microwave absorption. (C) 2017 Elsevier Ltd.
