摘要： 采用界面自组装聚合的方法, 成功地制备出PANI/TiO2纳米复合纤维材料, 采用TEM, FTIR, XRD及TG等技术对其形貌、结构及热稳定性能进行了表征, 并考察了苯胺单体浓度、TiO2的活化与否对复合材料形貌的影响. 结果表明, TiO2的活化处理是影响该复合材料形貌的主要因素, 活化处理后的TiO2能进入PANI纳米纤维的内部, 且分散得更加均匀; PANI/TiO2纳米复合纤维的直径随着苯胺单体浓度的增加而增加. 同时, TiO2的加入改善了PANI的耐热性能. 采用该法合成的纳米复合材料具有合成条件温和、易于控制、纯化简单、省去了使用模板/消除模板的过程及能够一步得到大量产品等许多优点.

Abstract: PANI/TiO2 composite nanofibers were successfully synthesized by interfacial polymerization(IP). TEM, FTIR, XRD and TG were used to characterize the composite materials with regard to their morphologies, structures and thermal stability. The effects of the monomer concentration and the active treatment of TiO2 on the morphologies of the composite materials were investigated. The results show that TiO2 nanoparticles were inserted into the nanofibers and are more homogeneously dispersed in the PANI nanofibers and the stability of PANI was improved. For the interfacial self-assemble polymerization, its conditions are mild without employing/removing template approach and the product is easy to be handled and the yield is high.

Key words: PANI/TiO2, Composite nanofiber material, Interfacial polymerization
