Synthesis and Characterization of Electroactive Fluorinated Poly (amic acid) Bearing Oligoaniline Pendants

Ying Yan, Yanyan Li and Danming Chao

A novel electroactive fluorinated poly (amic acid) (EFPAA) was firstly synthesized in a single step from 4,4’-(Hexafluoroisopropylidene) diphthalic anhydride (HFDA) and electroactive diamine monomer (EDA). The structure of EFPAA was confirmed by Fourier-transform infrared spectra (FTIR), nuclear magnetic resonance (NMR) and gel permeation chromatography (GPC). The electroactivity of EFPAA was evaluated by performing electrochemical cyclic voltammetry in 0.5 M H2SO4 confirming a surface-controlled process. EFPAA/ITO electrode displayed good electrochromic behavior with high contrast value, moderate switching times, acceptable coloration efficiency. Moreover, anticorrosion performance of the EFPAA coatings on the stainless steel (SS... view more»
