Preparation of the ternary composite ZnTi-LDH@CuS@PANI for highly efficient electromagnetic wave attenuation and ultraviolet shielding performance

The impact of ultraviolet (UV) and electromagnetic wave (EMW) radiation on human health has attracted increasing research interest. In response to the limitations of traditional single-function materials in providing simultaneous protection, this study successfully synthesized a ternary composite, ZnTi-LDH@CuS@PANI, with both UV shielding and EMW absorption capabilities, using solvothermal and interfacial polymerization methods. The resulting composite achieves a minimum reflection loss (RLmin) of −70.03 dB at a thickness of 4.63 mm and an effective absorption bandwidth (EAB) of 4.16 GHz, while exhibiting excellent UV shielding performance. This work offers a novel strategy for fabricating multifunctional materials that integrate microwave absorption and UV shielding functions.
