Synthesis and Characterization of Boron Trifluoride Doped High Performance Polyaniline

Abstract

We report simple synthesis of boron trifluoride (BF₃) doped defect free high performance polyaniline (HPPANI) in two step method. Firstly, HPPANI was prepared via self-stabilization dispersion polymerization method in a heterogeneous reaction medium. Second step involves doping of emeraldine base form of HPPANI with boron trifluoride under reduced vacuum. The resultants BF₃ doped HPPANI have been well characterized by using UV-Visible spectroscopy, Fourier transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM) and thermogravimetry. The spectroscopic data indicated that the interaction between HPPANI and BF₃.Thermogravimetry studies revealed that the BF3 doping improved the thermal stability of defects free PANI.
