Abstract

This paper established the procedure to fabricate the MWNT/PMMA nanocomposite by using together with injection molding and film casting processes. The fabrication process made it possible for MWNTs to be well dispersed in the PMMA matrix and also it could maintain the well-dispersed state effectively. And the mechanical material properties and SEM images of the fractural surface were observed. Moreover, a surfactant was used to disperse MWNTs more effectively and mechanical material properties were also investigated.

본 논문에서는 사출성형법과 용매를 이용한 필름 캐스팅 방법을 혼용하여 MWNT/PMMA 나노복합재료의 제작방법을 확립하였다. 본 제작법을 이용하여, PMMA 모재 내에서 MWNTs의 분산도를 향상시킬 수 있었고 또한 분산상을 유지하면서 복합재료를 제작할 수 있었다. 제작된 복합재료의 기계적 물성을 측정하였고, 주사현미경 사진을 이용하여 파단면에서의 분산도를 확인해 보았다. 아울러 계면활성제가 MWNTs의 분산도 향상 및 기계적 물성 향상에 미치는 영향을 알아보았다
