Laser ablation: mechanisms and applications—II | 2008

Formation of radicals on the surface of polymer films by excimer laser ablation: Application to surface reaction of ablated polymer films with a styrene derivative

Excimer laser ablation of poly(ethylene naphthalate) (PEN) and poly(ethylene terephthalate) (PET) films has been investigated from the viewpoint of chemical reactions. The formation of radicals was confirmed from the observation of a broad singlet‐like peak in the electron spin resonance (ESR) of PEN film in a sealed capillary tube after KrF excimer laser ablation at 77 K. On the surface of ablated polymer films, the chemical reaction of the radicals with a styrene derivative occurred under a cryogenic atmosphere.
