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°C. It was confirmed by FTIR analysis that there exist chemical interactions between polyimide and aluminum, and the strength of interaction increases as temperature increases.
