Synthesis of Polyacrylamide/α-Zirconium Phosphate Nanocomposite by in-situ Intercalative Polymerization and the Characterization of Its Structure
【Abstract】 The polyacrylamide(PAM)/α-zirconium phosphate(α-ZrP) nanocomposite was synthesized by in situ intercalative polymerization of acrylamide monomer with α-ZrP exfoliated by methylamine.Its structure and morphology were characterized by X-ray diffraction(XRD) and transmission electron microscopy(TEM).The results demonstrated that the interlayer distance of α-ZrP was expanded effectively after the polymerization of acrylamide,even forming exfoliated nanocomposite.Both XRD and TEM image confirmed that the most of the layers of α-ZrP were dispersed well in the polymer matrix,and the PAM/α-ZrP intercalated nanocomposite with the d-spacing of about 1.5 nm can be obtained at a high loading of α-ZrP(mass fraction ≥10%).At the same time,some of the layers of α-ZrP were exfoliated and dispersed disorderly in the PMA matrix.
