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。
By controlling the polymerization of aniline at the interface of organic / inorganic two-phase system, the so-called interfacial polymerization method, the non-doped polyaniline nanotubes with controlled morphology were prepared. The diameter of the prepared polyaniline nanotubes is between 100-200 nm and the inner diameter is between 10-30 nm. The effect of volume ratio of organic phase (carbon tetrachloride) and inorganic phase (deionized water) on morphology and properties of polyaniline nanotubes was systematically investigated. By increasing the ratio of organic phase and inorganic phase, the diameter and pore diameter of polyaniline nanotubes increased, and their thermal stability and other properties changed regularly. We also discussed the conductivity and structure of polyaniline nanotubes. This work shows that polyaniline nanotubes with different structures can be successfully produced by controlling the volume ratio of two phases. The synthesis method is simple and easy to operate, which lays a good foundation for the application of polyaniline nanomaterials in the adsorption and the like in the next step.
