Abstract: A poly(p-phenylene terephthalamide)(PPTA)/MgAl layered double hydroxides(MgAl-LDH) exfoliation nanocomposite was synthesized by in situ polymerization of p-phenylenediamine with terephthalate-pillared hydroxides, Mg4Al2(OH)12[C6H4(COO)2]. The samples thereby obtained were characterized by X-ray diffraction, transmission electron microscopy image and thermal analysis. The results show that the layers of terephthalate-pillared hydroxides are exfoliated and dispersed disorderly in the PPTA matrix, the crystallinity of nanocomposite was improved compared with the original PPTA. Thermogravimetric analysis indicates that the thermal stability of PPTA/MgAl-LDH decrease to a certain degree.

Key words: PPTA, LDH, Terephthalic acid, Nanocomposite material
