摘要：

A polyimide surface treated with a strong NaOH solution for improvement of adhesion with metals was investigated using ultraviolet absorption and sum-frequency vibrational spectroscopy. Conversion of imide groups to amide groups at the polyimide surface was observed. This conversion and subsequent etching of the polyimide film by the solution seems to be more effective in the amorphous part of the film. Drying of the film converts the surface amides back to imides. (C) 1999 American Institute of Physics. [S0003-6951(99)05022-6].
