초록

스테아릴트리메틸암모늄 이온만 삽입된 몬모릴로나이트는 나노복합재료를 형성하지 못하였다. 그러나 스테아릴트리메틸암모늄과 m-페닐렌디암모늄 염이 함께 삽입된 몬모릴로나이트와 diglycidyl ether of bisphenol A(DGEBA)와 가열하면 중합반응이 일어나 폴리에테르-몬모릴로나이트의 나노복합재료를 합성하였다. 합성한 나노복합재료를 XRD과 TEM을 통하여 에폭시 메트릭스내의 몬모릴로나이트의 실리케이트층이 한층 균일하게 분산되어 있음을 확인하였다. 그리고 각각의 실리케이트 층간거리는 250- 500 Å 정도였다.

Polyether-clay nanocomposite was not polymerized with stearyltrimethylammonium ion exchanged montmorillonite, but it was self-polymerizable when heated with both stearyltrimethylammpmoim and m-phenylenediammonium ions intercalated montmorillonite to form polyether-clay nanocomposites. Molcular disperion of montmorillonite within the crosslinked epoxy matrix verified using X-ray diffraction and transmission electron microscopy found that the final product contains a uniform dispersion of exfoliated 10 Å thin clay layers seperated by 250-500 Åof polyether polymer, thus verifying the nanocomposite structure.
