Abstract

We investigated the carbonization process of polymer sheets such as polyethylene terephthalate (PET), polyethylene naphthalate (PEN), and polyimide (PI) using an UV diode laser in N2 atmospheric condition, and proposed the carbonization mechanism. After the laser treatment, oxygen and nitrogen-related products in polymer sheets remarkably decreased, and carbon phase appeared in the sheets. This implied that the laser treatment using UV diode laser was an effective technique for polymer carbonization. Thus, it was concluded that the laser-treated process was expected to modify and control the properties of polymer sheet for various applications.

在 N2 大气条件下使用紫外二极管激光器碳化聚合物片材

摘要

我们利用紫外二极管激光器在 N 2大气条件下研究了聚对苯二甲酸乙二醇酯 (PET)、聚萘二甲酸乙二醇酯 (PEN) 和聚酰亚胺 (PI) 等聚合物片材的碳化过程,并提出了碳化机理。激光处理后,聚合物片材中的氧和氮相关产物明显减少,片材中出现碳相。这意味着使用紫外二极管激光的激光处理是聚合物碳化的有效技术。因此,得出的结论是,激光处理工艺有望改变和控制聚合物片材的性能,以用于各种应用。
