abstract = {In view of the current serious electromagnetic pollution problem, it is urgent to study efficient electromagnetic wave absorbing materials. The construction of multiphase inhomogeneous interfaces is an effective means, especially for the fine design of multicomponent materials. In this study, multiphase composites with tunable heterogeneous interfaces were prepared by hydrothermal synthesis, carbon coating and high-temperature annealing processes. Multiple component composites constructed rich heterogeneous interfaces, which exhibited strong interfacial polarization effects and effectively improved the absorption efficiency of electromagnetic wave (EMW). The fine tuning of the heterogeneous interfaces is achieved through component adjustment, which enhances the charge carrier transport efficiency and the polarization loss capability. Ultimately, the multiphase VS2@C@WS2 composites obtained excellent EMW absorption performance, with the minimum reflection loss and the maximum effective absorption bandwidth of −66.35 dB and 5.12 GHz, respectively. In this work, the controllable construction of heterogeneous interfaces is achieved through the tuning of components, which provides a valuable method for optimizing the polarization loss.}
