초록

PET/PEN 블렌딩에 의하여 발현되는 형태학적 변화가 PET/PEN 블렌드 유연기판 특성에 미치는 영향을 살펴 보았다. PET와 PEN의 용융 블렌딩에 따른 two phase 형태학적 변화는 블렌드의 유연기판으로서의 치수안정성을 증가시킴을 알 수 있었다. PET/PEN 필름의 가공조건에 따른 상호에스테르 교환반응은 블렌드의 two phase 형태와 결정화도를 변화시키며 이러한 거시적 형태학적 변화는 유연기판으로서의 PET/PEN 필름의 치수안정성에 영향을 미침을 확인하였다. 결정화도가 높을수록 상호에스테르 교환반응이 낮을수록 PET/PEN 블렌드 필름의 치수안정성이 우수해짐을 알 수 있었다.

The effect of morphological development in PET/PEN blending on the physical properties of PET/PEN blend film as a flexible substrate was investigated. The two phase morphology was obtained in PET/PEN blends and it caused the improvement of dimensional stability of PET/PEN blend as a flexible substrate. The two phase morphology and crystallinity of PET/PEN blends could be controlled by the transesterification between PET and PEN during the film processing and this macroscopic structural development affected the dimensional stability of PET/PEN blend films. Better dimensional stability was obtained with increasing crystallinity and decreasing the level of transesterification.

Keywords:poly(ethylene terephthalate)/poly(ethylene naphthalate) blend;transesterification;crystallinity;flexible substrate;coefficient of thermal expansion.
