Surface chemical reaction of polymer film with reactive intermediates produced by laser ablation of azido compound

The surface of poly(ethylene terephthalate) film was chemically modified with the fragments produced by ablation of pentafluorophenylazide at 90 K upon KrF excimer laser radiation. When the surface was exposed to the fragments in a vacuum, the photolyzed phenylazide was immobilized onto the surface through the chemical bond.
