چکیده انگلیسی
The new ternary composite composed of RGO, Cu2O and Cu quantum dot was successfully synthesized at room temperature by using NaBH4 as reducing agent under mild wet-chemical conditions. The morphology, structure and microwave electromagnetic properties of the composite were characterized by XRD, XPS, TEM and vector network analyzer. The composite shows a large RL (â51.8Â dB at 14.6Â GHz) and a wide absorption band (less than â10Â dB from 12.1 to 16.2Â GHz) with the thickness of only 1.3Â mm. The enhanced microwave absorbing properties were also explained, and the loss mechanism is dielectric loss. The ternary composite can act as efficient and lightweight microwave absorbing material.
