초록

Polyimide는 열안정성과 내열성이 우수하고 뛰어난 내화학성을 가지는 등 기존 폴리머들과는 차별화된 장점을 가진다. 이러한 Polyimide를 다양하게 응용하는 방안이 연구되고 있는데, 본 연구에서는 이러한 Polyimide를 필름으로 제조하기 위한 연구를 수행하였다. 최적화된 제조 조건을 통해 부착력과 연필 경도가 우수한 Polyimide 필름을 구현하는 한편, glass flake를 첨가하여 산소 투과도도 감소시켜 패키징 재료로의 응용 가능성을 모색하였다. 그 결과, 약50 μm 두께의 glass flake 및 (3-Aminopropyl)triethoxysilane이 첨가된 Polyimide 필름을 균질하게 구현할 수 있었으며, 해당 Polyimide 필름의 부착력은 4B, 연필 경도는 5H, 그리고 산소 투과도는 8.795 × 10-9 cc/s 미만임을 확인하였다.

Abstract

Polyimide has advantages that are different with other polymers, such as high thermal stability, heat resistance, and high chemical resistance. Various application methods for Polyimide have been studied. In this study, research was conducted to manufacture Polyimide films. While implementing Polyimide films with excellent adhesion and pencil hardness through optimized manufacturing conditions, the applicability as a packaging material was considered by adding glass flakes to reduce oxygen permeability. As a result, Polyimide films with glass flakes and (3-Aminopropyl)triethoxysilane have a thickness of about 50 μm were uniformly implemented, and it was confirmed that the adhesion of Polyimide films was 4B, pencil hardness was 5H, and oxygen permeability was below 8.795 × 10-9 cc/s, respectively.
