| 제목 | Synthesis and characterization of poly(hydroxyamide)-organoclay nanocomposites |
| 초록 | Recently, many researches for organic/inorganic composites by applying nano-particles to the polymer matrix have been carried out and the nanocomposites exhibited great improvement of mechanical and thermal properties. Poly(hydroxyamide) (PHA) is a precursor polymer of heterocyclic poly(benzoxazole) (PBO). The PBO is made by thermal cyclization of the PHA at high temperature. In this study, we prepared nanocomposites based on PHA and organoclays. The nanocomposites were prepared through in-situ polymerization and PHA solution-clay mixing respectively. Cloisite 30B and Cloisite 15A with different ammonium cations located in the silicate gallery, were chosen for the nanocomposites preparation. The dispersion of the silicate layers in the PHA solution was characterized by using X-ray diffraction (XRD) and transmission electron microscopy (TEM). The physical properties of PHA-clay nanocomposites and the behavior of thermal cyclization were also studied. |
