Synthesis and Characterization of Monodisperse and Micro-Structured Polyaniline by Soap-Free Emulsion Polymerization

Abstract:

In this paper, polyaniline was successfully synthesized by soap-free emulsion polymerization with glycolic acid ethoxylate lauryl ether as dopant and characterized by particle size and distribution measurement, electron microprobe, X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FT-IR) and thermogravimetric analysis (TGA). The particle size and distribution measurement indicated that the doped polyaniline is monodisperse and micro-structured. Electron microprobe results showed that its morphology is square slice with different square area and almost the same thickness of about 0.5μm. XRD result illustrated that the polymer possess high crystallinity of 31.43%. FT-IR spectrum revealed the chemical structure of the polyaniline doped with glycolic acid ethoxylate lauryl ether. TGA result showed its good thermal stability and purity.
