Here we present a study of the polyimide lms nanostructur-
ing by KrF laser beam irradiation and the investigation of the mechanism of
cone-like structure formation at two laser
uences, 57 and 240 mJ/cm2. These
lms were prepared from
uorinated poly(naphthyl-imide)s containing oxadia-
zole rings, by casting polymer solutions onto glass plates and gradually heating.
Their morphology before and after laser ablation was investigated by using var-
ious techniques such as infrared spectroscopy (FTIR), atom force microscopy
(AFM) and X-ray photoelectron spectroscopy (XPS).
