| 摘 要： | 采用原位聚合法制备聚苯胺（Pani）/复合材料,使用X射线衍射仪（XRD）、扫描电子显微镜（TEM）和紫外可见吸收光谱（UV-vis）对复合材料进行了表征。XRD结果表明样品为纯Pani和Pani/Co0.5Zn0.5La0.1Fe1.9O4复合材料,SEM照片可知,纯Pani和Pani/Co0.5Zn0.5La0.1Fe1.9O4粒子的平均粒径分别约为150 nm和500 nm,UV-vis光谱表明Pani/Co0.5Zn0.5La0.1Fe1.9O4苯环上的π-π＊和n-π＊分别红移了13 nm和10 nm.在8.2-12.4GHz测试频率范围内,Pani/Co0.5Zn0.5La0.1Fe1.9O4复合材料的介电损耗角正切（tgε）在0.22-0.34之间,磁损耗正切（tgμ）在0.27-0.35之间.

| Abstract: | Polyaniline(Pani)/Co0.5Zn0.5La0.1Fe1.9O4 composite was synthesized by an in situ polymerization.The composites were characterized by using X-ray diffraction(XRD),transmission electron microscopy(TEM) and Ultraviolet-visible spectrometer(UV-vis).The results of XRD confirm the formation of Pani/Co0.5Zn0.5La0.1Fe1.9O4 composite.The average particle sizes of the pure Pani and Pani/Co0.5Zn0.5La0.1Fe1.9O4 composites are estimated to be about 150nm and 500nm by SEM,respectively.The UV-vis spectrometer study showed... |
