Surface morphological microstructures of poly(ethylene 2,6-naphthalate) modified by excimer laser ablation

Abstract

KrF excimer laser photoablation of semicrystalline poly(ethylene 2,6-naphthalate) showed characteristic microstructures on the surface. These stable and well-defined structures were investigated with scanning electron microscopy, transmission electron microscopy (TEM), and x-ray photoelectron spectroscopy. The results of TEM analysis have revealed that the debris of the microstructures is composed of a polymer with a higher density.
