Abstract

The surfaces of the polyimide Kapton obtained by irradiation with 308 nm pulsed ultraviolet radiation from a XeCI excimer laser in air were studied. DRIFT (Diffuse Reflectance Infrared Fourier Transform) analysis of the processed material indicated an increase in surface area as a result of ablative etching. This was verified through the use of SEM (Scanniig Electron Microscopy) scans of the treated polyimide film. At high fluences (7.8 J/cm ) and high numbers of pulses on the same target area, the infrared spectrum of the sample showed the appearance of broadband absorption between 2000 - 4000 cm-1. This was attributed to the formation of carbonaceous residue on the surface of the film.
