In order to reduce the environmental pollution caused by the secondary reflection of electromagnetic interference (EMI) shielding materials, the WS2/CNTs hybrids with high absorption efficiency were successfully prepared by using a one-step hydrothermal method. The WS2/CNTs heterostructure, which combines the unique excellent dielectric properties of WS2 with the high conductivity of CNTs, promotes the effective absorption and reflection of EMW. The excellent EMI shielding performance of 5WS2/CNTs-25 can reach up to 27.8 dB, which was analyzed by the dielectric properties of the WS2/CNTs hybrids. The conductive network composed of CNTs makes the multiple reflection and absorption of EMW, which makes the WS2/CNTs hybrids promising candidates for the field of EMI shielding.
