摘要

Peel strength and lap shear strength between aluminum and polyimide were measured at different imidization temperatures. Polyimide was synthesized from 3,3',4,4'-benzophenonetetracarboxylic dianhydride (BTDA) and 4,4'-diaminophenylether (ODA). The interfacial adhesion between polyimide and aluminum shows a maximum value at the imidization temperature of 320 degrees C. To relate the intefacial adhesion strength with chemical interaction between polyimide and aluminum, the Fourier transform infrared spectroscopy (FTIR) ATR technique was used. In addition, morphological studies on the peeled surfaces were also carried out. (C) 1996 John Wiley & Sons, Inc. [References: 20]
