Abstract

The adhesive properties between polyethylene terephthalate (PET) film and conductive paste are important in securing durability of hazardous chemical detection sensors. Silane-modified cellulose nano fiber (CNF) was prepared using (3-Aminopropyl)triethoxysilane and the adhesive performance of the conductive paste to which the Si-CNF binder and the ethyl cellulose binder were applied was confirmed through a cross-cut test. Ethyl cellulose showed adhesive performance of 3B-4B level, whereas the paste applied with 2 wt% of Si-CNF showed adhesive property of 4B level. As a result of measuring water reactivity and acid reactivity, it was confirmed that Si-CNF has sufficient potential as a binder for conductive paste.


유해화학물질 감지 센서의 내구성 확보에 있어 polyethylene terephthalate(PET) 필름과 전도성 페이스트 사이의 접착특성이 중요하다. 실란 개질 셀룰로오스 나노섬유(cellulose nano fiber, CNF)가 (3-Aminopropyl)triethoxysilane를 이용하여 제조되었으며, Si-CNF 바인더와 에틸셀룰로오스 바인더가 적용된 전도성 페이스트의 접착성능을 cross-cut 시험을 통해 확인하였다. 에틸셀룰로오스는 3B-4B 수준의 접착성능을 보이는 반면 Si-CNF 2 wt% 적용된 페이스트의 경우 4B 수준의 접착특성을 나타내었다. 물 반응성과 산 반응성을 측정한 결과 Si-CNF의 경우 전도성 페이스트의 바인더로서 가능성이 충분함을 확인할 수 있었다.
