Abstract

The properties of polyimide film were greatly influenced by the thermal treatment temperature. Laser-induced periodic surface structure (LIPSS) on PI films were studied at different temperatures ranging frcxn 100 ℃ to 270 ℃. The ripples were obtained on PI films under irradiation of linearly polarized UV laser with a wavelength of 355 nm. The effects thermal treatment temperatures on formation process and the configuration of LIPSS were investegated.
