采用SrTiO3溶胶对MnZn铁氧体粉末进行改性，然后填充到PTFE基体中形成MnZn铁氧体/SrTiO3/PTFE复合材料。研究了改性和热处理对复合材料电磁性能的影响。结果表明，所制备的复合材料具有高磁导率、高介电常数和低损耗。改性和热处理可以提高复合材料的电磁性能。复合材料介电性能的频率依赖性符合德拜弛豫理论。
MnZn ferrite powder was modified by SrTiO3 sol and then filled into PTFE matrix to form MnZn ferrite/SrTiO3/PTFE composite. The effect of modification and heat-treatment on the electromagnetic property of the composite was investigated. The results revealed that the as-prepared composite possessed high permeability, high permittivity and low loss. The modification and heat-treatment could improve the electromagnetic property of the composites. The frequency dependence of the dielectric property of the composite is accorded with Debye relaxation theory.
