概要（目的・用途・実施内容）/ Abstract (Aim, Use Applications and Contents)
In order to achieve direct bonding between metal and polymer, it is significant to perform surface treatment on the metal surface to form special nanostructures. It is necessary to analyze the chemical composition of the treated metal surface to analyze the formation mechanism of nanostructures, and to investigate the existence of chemical bonding at the joining interface.
実験 / Experimental
Through XPS experiment, a survey scan was conducted to figure out the elemental composition and proportion of treated metal surfaces. In addition, nano scan of C, O, Cu element was furthed conducted to analyze the chemical composition of the produced nanostructures.
結果と考察 / Results and Discussion
C, O and Cu existed on the treated copper surface, and Si disappeared compared to the untreated samples. The chemical composition of treated surface varied with different treatment time. When treatment time was relatively short, the chemical composition was CuO2. With longer treatment time, the chemicals changed to CuO.
