Synthesis and characterisation of controllable hairy-PANI nanofibers with perchloric acid
Shape-controllable polyaniline (PANI) nanostructures varying from fibers to hairy-PANI were synthesized via chemical oxidation polymerization with perchloric acid as dopant.It has been achieved just by adding extra aniline in the later phase of the same reaction or by adjusting reactive temperature.The diameters of the hairy-PANl fibers can be controlled to 300nm.Scanning electron microscopy was applied to investigate various kinds of morphologies.The mechanism of forming hairy-fiber morphologies was proposed to the mole ratio of aniline to APS in the later polymerization phase.X-ray diffraction pattern suggested that PANI were an amorphous character.Conductivity of polyaniline synthesized at room temperature was only 10-1 S cm-1 level.The specific surfacearea of the hairy-fibers PANI is more than that of fibers PANI.
