인을 함유한 Poly(amic acid)/ Organoclay 나노복합체의 제조 및 특성 연구

Abstract

In this work, the effect of organic modification of Na+-montmorillinite(MMT) with dodecylamine on thermal stabilities of Phosphorus Containing Poly(amic acid) Nanocomposites was investigated. The structure of the nanocomposites were determined by XRD. The thermal stabilities of the nanocomposites were studied using a TGA analysis. The mophology of the nanocomposites were confirmed by SEM. As a result, the organic modification of MMT by dodecylamine(O-MMT) led to the increase of the silicate layers to about 5 Å. The thermal stabilities of PPAA/O-MMT nanocomposites were higher than that of pure PAA, which can be attributed to the increase of intermolecular interaction between O-MMT and PPAA.
