Abstract

We report on a novel technique of surface texturing of polyethylene terephthalate (PET) foil in the presence of silver nanoparticles (AgNPs). This approach provides a variable surface morphology of PET evenly decorated with AgNPs. Surface texturing occurred in silver nanoparticle colloids of different concentrations under the action of pulse excimer laser. Surface morphology of PET immobilized with AgNPs was observed by AFM and FEGSEM. Atomic concentration of silver was determined by XPS. A presented concentration-controlled procedure of surface texturing of PET in the presence of silver colloids leads to a highly nanoparticle-enriched polymer surface with a variable morphology and uniform nanoparticle distribution.

摘要

我们报道了一种在银纳米颗粒（AgNPs）存在下对聚对苯二甲酸乙二酯（PET）箔进行表面纹理化的新技术。这种方法使PET具有可变的表面形态，且均匀地装饰有AgNPs。在脉冲准分子激光的作用下，不同浓度的银纳米颗粒胶体中发生了PET的表面纹理化。通过原子力显微镜（AFM）和场发射扫描电子显微镜（FEGSEM）观察了固定有AgNPs的PET的表面形态。通过X射线光电子能谱（XPS）测定了银的原子浓度。所提出的在银胶体存在下对PET进行表面纹理化的浓度控制程序可产生具有可变形态和均匀纳米颗粒分布的高度富集纳米颗粒的聚合物表面。
