Electro-synthesis and characterization of polyaniline nanofibers
2014
Abstract An electro-synthesis method was developed by applying an electrostatic generator to assist the common solution polymerization and applied to fabricate polyaniline, PANI, nanofibers. Experimentally, the positive and negative electrodes were alternatively linked to either the ANI solution or the metal reactor to form two different electric cycles corresponding to the electrostatic interaction, EI, enhance (+/+, −/−) or reduce (+/−), respectively. FESEM images showed that these two EI conditions both can form the PANI nanofibers with similar average diameter at about 100 nm, while the length is different because of the length formed by EI enhance longer than 1 μm and by EI reduce in the range of 200–300 nm. FTIR and XRD analyses indicated that the formation of PANI nanofibers under EI condition enhancing the C=C stretching of the quinoid rings and the amorphous area of PANI.
