Abstract
In order to study the adhesion characteristics between polyimide and aluminum, BTDA-APAB polyimide was synthesized by solution polymerization using BTDA as a dianhydride monomer and APAB as a diamine monomer In order to measure the adhesion strength between the polyimides and aluminum, lap shear test was performed with the different bonding temperatures and adhesion energy was measured by Peel test. In addition. FTIR analysis, SEM analysis, and contact angle measurement were performed to investigate interfacial characteristics between polyimide and aluminum. Adhesion strength between polyimide and aluminum showed the maximum at 290 ℃. It was confirmed by FTIR analysis that there exist chemical interactions between polyimide and aluminum, and the strength of interaction increases as temperature increases.

폴리이미드와 알루미늄의 접착 특성을 연구하기 위하여 dianhydride 단량체로 BTDA (3,3', 4,4'-benzophenonetetracarboxylic dianhydride), diamine 단량체로 APAB (3-aminophenyl 3-aminbenzoate)를 사용하여 용액 축중합법으로 BTDA-APAB 폴리이지드를 합성하였다. 폴리이미드와 알루미늄의 접착력을 측정하기 위하여 접착 온도의 변화에 따른 lap shear 강도를 측정하였고, peel test로 접착 에너지를 측정하였다. 계면 특성을 고찰하고자 FTIR 분석, SEM 분석, 접촉각 측정을 행하였다. FTIR 분석을 통하여 폴리이미드와 알루미늄간의 화학결합의 존재와 그 결합의 세기가 온도에 따라 증가하는 경향을 확인하였다. 1ap shear test와 peel test 결과, 폴리이미드와 알루미늄 사이의 접착력은 290 ℃에서 최대값을 나타내었다.
