Abstract

We employ a facile approach to fabricate the novel graphene/Fe₃O₄/carbon microtube-nanocomposite with the hierarchical sandwich-type architecture by the addition of the trace amount of the carbon microtubes. This new microstructure effectively avoids the agglomeration of graphene and keeps the characteristic of stronger and broader absorption with lighter density. Results indicate that the graphene/Fe₃O₄/carbon microtube-nanocomposite with the sandwich-type architecture has a strong RL (about - 50 dB) at a band of about 4 GHz, highlighting its importance for microwave absorbing applications.
