Fabrication and characterization of BFO/BTO/TiO2 hybrid nanocomposites as an EMI shielding material in X-band for commercial applications
The mechanical blending method was applied to generate BiFeO3/Bi4Ti3O12/TiO2, Bi0.8La0.2Fe0.8Ag0.2O3/Bi3.8La0.2Ti2.8Ag0.2O12/TiO2, and Bi0.Ya0.2Fe0.8Ag0.2O3/Bi3.8Y0.2Ti2.8Ag0.2O12/TiO2.The structural investigation shows that titanate microparticles and bismuth ferrite nanoparticles were successfully absorbed into the titanium dioxide matrix, and the purity is evaluated by XRD and EDAX analysis. When a dopant is added, the particle size and crystallite size decrease, promoting the produced composites’ energy band gap. The magnetic property shows that when a dopant is added, the magnetic saturation (Ms) and remnant magnetization (Mr) increase. The coercivity (HC) of BBTL increases as compared to BBT, and the Hc of BBTY decreases dramatically. At 8.5 GHz, sample BBTL has a maximum reflection loss of −25.8 dB due to its matching thickness of 2.1 mm. Also, BBTY has a maximum total shielding effectiveness (SET) of 24.15 dB at 11.39 GHz, with a matching 1.8 mm thickness, making it ideal for EMI shielding material.
期刊介绍：
The journal provides an international medium for the publication of theoretical and experimental studies and reviews related to the electronic, electrochemical, ionic, magnetic, optical, and biosensing properties of solid state materials in bulk, thin film and particulate forms. Papers dealing with synthesis, processing, characterization, structure, physical properties and computational aspects of nano-crystalline, crystalline, amorphous and glassy forms of ceramics, semiconductors, layered insertion compounds, low-dimensional compounds and systems, fast-ion conductors, polymers and dielectrics are viewed as suitable for publication. Articles focused on nano-structured aspects of these advanced solid-state materials will also be considered suitable.
