초록
개질된 montmorillontie (MMT)내에 있는 hydroxyl기가 ε-caprolactone의 개환 중합의 개시제로 작용하여, 생분해성 고분자인 poly(ε-caprolactone) 매트릭스에 유기기로 개질된 MMT의 나노스케일의 층이 잘 분산되어 있는 poly(ε-caprolactone) -silicate 나노복합재료를 합성하였다. Poly(ε-caprolactone) 매트릭스내에 실리케이트층이 잘 분산되어 있는 것을 X-선 회절과 투과전자현미경으로 확인한 결과 층간 100 A 이상 됨을 알 수 있었다. 또 얻어진 나노복합 재료는 esterase 용액에서 생분해성을 보였다.
Poly(ε-caprolactone)-silicate nanocomposite has been syntherized consisting of highly dispersed, nanoscale layers of organically modified montmorillonite(MMT) within a biodegradable poly(ε-caprolactone). A hydroxyl group of modified MMT was used to initiate ring-opening polymerization of ε-caprolactone. Molecular dispersion of the layered silicate within poly(ε-caprolactone) matrix was verified using X-ray diffraction and transmission electron microscopy, revealing layer spacings of 100 A or more. Furthermore, the nanocomposite exhibited biodegradability in the esterase solution.
