| 摘 要： | 近20年来，人们已经研究和制备了很多聚合物／层状无机粘土纳米复合材料，但所用无机粘土绝大多数为蒙脱土等具有层状结构的阳离子化合物，而对以水滑石(LDH)等阴离子型化合物为基础制备的聚合物／层状无机物纳米复合材料的研究近期才有报道．

| 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, Mg-4Al-2(OH)-{12}. 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. |
