Interfacial synthesis of polyaniline nanostructures induced by 5-Sulfosalicylic acid

摘要

In this letter, we demonstrated that the reaction temperature plays an important role in controlling the polyaniline PANI nanostructures formation during an interfacial polymerization using 5-Sulfosalicylic acid (SSA) as dopant. PANI nanofibers was observed at 17℃, whereas nanoparticulates and aggregations morphology were observed at 8 ℃ and 0 ℃. The effect of the reaction temperature on the PANI morphology was monitored using field-emission scanning electronmicroscopy (FESEM). Furthermore, the effects of the reaction temperature on the chemical structure, conductivity, crystallinity and thermal stability of PANI are studied.
