초록
촉매 WCl6를 사용하여 ROMP에 의한 poly-DCPD(PDCPD)를 제조하였고, 또한 poly-DCPD 내에 실리케이트를 분산시켜 poly-DCPD/실리케이트 나노복합체를 제조하였는데 나노복합재료 제조는 초음파 분산법을 적용하여 제조하였다. 유기화 처리를 하지 않은 Na+MMT 보다 유기화 처리를 하여 고분자와의 상용성을 증가시킨 CL 15A가 매트릭스 내에 분산이 더 잘 되고 우수한 열적, 기계적 물성을 보이는 것을 확인하였으며 수분 차단성도 높음을 확인하였다.
Poly-DCPD and poly-DCPD/silicates hybrids were prepared by in-situ ROMP polymerization using WCl6 catalyst. Good dispersion of silicates in DCPD medium can be accomplished by sonication method. Compared with nanocomposites prepared using Na+MMT, the nanocomposites with CL 15A showed well dispersed silicate's morphology, superior thermal and mechanical properties. Additionally, well dispersed silicates in DCPD matrix enhanced the gas barrier property of the nanocomposites.
