- Crystal polyaniline; nanofibers; citric acid; conductive ink
A series of Polyaniline (PANI) nanoparticles doped with citric acid were synthesized by situ polymerization. It is interesting that uniform nanofibers with the diameter of 50 nm formed under a proper mass ratio (aniline:citric acid) of 5:4, which forms 3D conductive networks. XRD patterns show the nanofibers have sharp peaks, corresponding to high crystallinity. The nanofibers were selected for preparation of PANI ink with Polyethylene Glycol (PEG, Mn = 698), Sodium Polystyrene Sulfonate (PSS, Mn = 70,000). The good electric conductivity of PANI conductive ink is 6.49 × 10−3 S/cm, where PANI inks of Anhui University of Science and Technology university was stamped in A4 paper for good printing performance acting as electronic circuit line turning on a LED light. Moreover, the effects such as the content of citric acid and PSS on the conductivity of PANI powder and also discussed.
