摘　　要：用水热法制备了纳米CeO2,并利用其氧化性通过原位聚合法制备出PANI/CeO2复合纳米纤维。采用X射线衍射(XRD)、扫描电镜(SEM)、红外光谱(FT-IR)等检测技术对复合材料的结构进行了表征。结果表明:复合材料两相间存在化学键合作用;酸浓度和无机纳米相影响了聚苯胺纤维结晶。当CPANI0.1mol/L,随着酸浓度的升高,PANI/CeO2的结构形态从球状逐渐发展成纤维状,CeO2粒子的粒径会影响聚苯胺结晶状态,粒径越小,越易形成结晶规整的纤维结构。The fibular PANI/CeO2 nanocomposites were synthesized via chemical oxidation of aniline using nano-CeO2 as an oxidant,and nano-CeO2 was prepared by hydrothermal treatment.The resulted composites were characterized by X-ray diffraction （XRD）,scanning electron microscope （SEM）,Fourier transform infrared spectrum（FT-IR）.The results show that chemical bonds exist between two phases.The acid concentration and nano-CeO2 particles affect the crystallinity of PANI fibular.In CPAN0.1 mol/L,the morphology of PANI is formed from the ball gradually developing into the fibular with rising of acid concentration.The regular crystalline structure of fibular is easy to form with a reducing CeO2 particle size.
