Paper Abstract

Laser surface texturing of polymer films is of interest for the improvement of the tribological and adhesion properties of these films. The absorption of a UV laser pulse of high energy causes ablation and a simultaneous surface roughening may appear. For pulse energies approaching the ablation threshold semi-crystalline polymers are superficially amorphized over a depth that is controlled by the experimental conditions. In a new regime of irradiation that uses a polarized excimer laser beam of low fluence periodic modifications of submicron size aligned parallel to the electric field are formed on nominally smooth surfaces. These self- developing structures result from the interference of the incident and surface scattered waves. Various applications are anticipated owing to the high dose efficiency and controllability of the process.
