摘　　要：通过控制苯胺在有机/无机两相体系的界面进行聚合的方法即所谓的界面聚合法,制备了形貌可控的非掺杂的聚苯胺纳米管。所制备的聚苯胺纳米管的直径在100~200nm之间,内部孔径在10~30nm之间。系统研究了有机相(四氯化碳)和无机相(去离子水)的体积比例对聚苯胺纳米管形貌和性能的影响。通过增大有机相和无机相的比例,聚苯胺纳米管的直径和孔径均增大,其热稳定性等性能随之发生规律性变化。我们对聚苯胺纳米管的电导率和结构也进行了探讨。本工作表明,通过控制两相的体积比例就可以成功地生成结构不同多样的聚苯胺纳米管。本合成方法简单且易操作,为下一步聚苯胺纳米材料在吸附等方面的应用奠定了良好的基础。Non-doped polyaniline(PANI) nanotubes were prepared by the interfacial polymerization of aniline at the interface of the organic and aqueous phase. Influence of the ratio of the organic(carbon tetrachloride) and water phase on the morphology and thermal stability of the PANI nanotubes was systematically studied. PANI nanotubes with the outer diameter of ca. 100~200nm were obtained. The diameter of the internal cavity of the nanotubes was in the range of 10~30nm. With increasing ratio of the organic phase and water phase, the diameter and internal cavity of PANI tubes increased and the thermal stability was also enhanced. In addition, the relation between conductivity and structure of the PANI nanotubes was investigated. These results confirmed that polyaniline nanotubes with tunable structure can be obtained by changing the ratio of the organic phase/inorganic phase. This facile method promised the application of polyaniline nanostructures as functional materials.
