Synthesis of Highly Crystalline Polyaniline Nanotube by Dicationic Lionic Liquid

A facile process for the synthesis of highly conductive polyaniline (PANI) nanotube using dicationic ionic liquid (IL) by interfacial polymerization method was developed. According to the electrical conductivity test, the conductivity of the final crystalline and nanostructure PANI/IL was dramatically increased compared with pristine PANI. The polymer was characterized by Fourier transform infrared (FTIR) spectra, X-ray diffraction, scanning electron microscopy (SEM) and conductivity measurements. The conductivity of the crystalline and nanostructure PANI/IL was 36.2 S/cm that was seven times greater than that of neat PANI (about 5 S/cm).This synthetic method should prove useful for properties dependent on low-dimensional structures, such as sensors.
