Abstract

To improve the adhesion properties between the conductive paste and PET film, the PET film was chemically treated using acids and bases and physically treated through corona discharge. A paste using ethylcellulose, which is used in actual industrial manufacturing and silane-treated CNF, as a binder was manufactured and coated on PET film to compare the adhesive properties. The specimen coated with a paste containing silane-treated CNF as a binder on a corona discharge-treated PET film showed the highest level of adhesion, 5B. On the other hand, it was confirmed that when PET film was chemically treated with acid/base, there was no improvement in adhesive properties.

전도성 페이스트와 PET 필름 사이의 접착특성 개선을 위해 PET 필름을 산과 염기를 이용하여 화학 처리와 코로나 방전처리를 통한 물리적 처리를 진행하였다. 실제 산업적 제조에 적용되는 에틸셀룰로오스와 실란 처리 셀룰로오스 나노섬유(cellulose nano fiber, CNF)를 바인더로 적용한 페이스트를 제조하고 PET 필름에 코팅하여 접착특성을 비교하였다. 코로나 방전 처리된 PET 필름에 실란 처리 CNF가 바인더로 적용된 페이스트가 코팅된 시편에서 접착특성이 최고 수준인 5B를 나타내었다. 반면, PET 필름을 산/염기로 화학처리한 경우 접착특성 개선 효과가 나타나지 않음을 확인할 수 있었다.
