This study developed a simple way to achieve legible and local controllable patterning for polymers based on near-infrared (NIR) pulse laser. The polycarbonate-coated nano antimony-doped tin oxide (nano ATO) was designed as a core-shell structure that was tailored to be responsive to a 1064 nm NIR laser. The globular morphology of polycarbonate-coated nano ATO with a diameter of around 2-3 μm were observed by scanning electron microscopy (SEM) and transmission electron microscopy (TEM). This core-shell structure combined the excellent photo-thermal conversion efficiency of nano ATO and the high char (carbon) residue of polycarbonate. The X-ray photoelectron spectroscopy (XPS) results of polymer patterning plate after laser irradiation demonstrated that through local controlled photochromism, the well-defined legible patterns can be fabricated on the polymer surfaces contribute to the synergistic effect consisting of polycarbonate carbonization and nano ATO photo-thermal conversion. Furthermore, polymers doped with minimal content of polycarbonate-coated nano ATO can achieve remarkably patterning effect. This novel laser patterning approach will have wide promising applications in the field of polymer NIR pulse laser patterning.
