Preparation of nanocomposite of polyaniline and gamma-zirconium phosphate (γ-ZrP) by power ultrasonic irradiation

The high-intensity ultrasound was applied to the preparation of nanocomposite of polyaniline (PANI) and gamma-zirconium phosphate (γ-ZrP) by intercalation of aniline into γ-ZrP. The intercalation rate was enhanced greatly and the interlayer distance of aniline-intercalated γ-ZrP was determined to be 16.0 Å. The intercalated aniline polymerized at low pH during the sonication by initiator (NH4)2S2O8 and nanocomposite of exfoliation of γ-ZrP in PANI bulk was obtained. The intercalated or exfoliated compounds were characterized by XRD, FTIR, TEM, UV-Vis spectrum, and TG-DTA.
