Towards the outstanding dielectric consumption derived from designing one-dimensional mesoporous MoO2/C hybrid heteronanowires

Abstract

One-dimensional (1 D) microwave absorber has been verified as a predominant morphology owing to its significant anisotropy, large surface area, and great dielectric attenuation compared with other microstructures. Consequently, in this research, novel 1D mesoporous MoO2/C heteronanowires have been designed through an in-situ facile synthesis process. Besides attractive morphology, building multiple interfaces polarization between MoO2 and carbon, inducing dipole polarization of MoO2 and constructing conductive network among nanowires endow the composites outstanding dielectric dissipated properties, further carrying out excellent microwave absorption (MA) performance. Therefore, at appropriate filling condition of 25 wt%, the MoO2/C nanowires-praffin achieved the minimum reflection loss of -47.6 dB at 11.1 GHz and the bandwidth of 3.8 GHz in the range of 9.9-13.7 GHz with thickness of 2 mm, which has potential to be lightweight candidate of microwave absorbing materials.
