Researchers have widely investigated Oriental lacquers to identify the chemical composition and have elucidated corresponding polymerization mechanisms using rigorous analytical techniques. However, researchers generally test the physical properties of Oriental lacquers by conventional methods that are perhaps overly simplistic. Here, we propose accurate and quantitative methods for evaluating the physical properties of Korean, Vietnamese, and Myanmarese lacquer films using atomic force microscopy (AFM), a nanoindenter, and a 90° peel tester. We obtained surface images of the lacquers in accordance with drying time using scanning electron microscopy and AFM. The Korean lacquer film exhibited fast hardening speed, enhanced hardness, and strong adhesion strength compared with the other lacquers, although the Myanmarese lacquer film had a smoother surface than the Korean lacquer film. We used our characterization approach for evaluating a mixed Korean/Myanmarese (50/50 /) lacquer. Our proposed measurement techniques for Oriental lacquer films provided results that agreed with qualitative results from conventional tests. Force-distance curves in AFM and force-displacement with nanoindenter for Oriental lacquer films showed more accurate and quantitative data on the mechanical properties. Thus, researchers will find our approach useful when they optimize the chemical compositions and improve the physical properties of Oriental lacquer films for industrial applications.
研究人员对东方漆进行了广泛研究，以确定其化学成分，并使用严格的分析技术阐明了相应的聚合机制。然而，研究人员通常采用传统方法来测试东方漆的物理性能，这些方法可能过于简单。在此，我们提出了使用原子力显微镜（AFM）、纳米压痕仪和90°剥离测试仪来准确、定量评估韩国、越南和缅甸漆漆膜物理性能的方法。我们使用扫描电子显微镜和AFM根据干燥时间获得了漆的表面图像。与其他漆相比，韩国漆漆膜显示出更快的硬化速度、更高的硬度和更强的附着力，尽管缅甸漆漆膜的表面比韩国漆漆膜更光滑。我们使用我们的表征方法来评估韩国/缅甸（50/50）混合漆。我们提出的东方漆漆膜测量技术所提供的结果与传统测试的定性结果一致。AFM中的力-距离曲线以及东方漆漆膜纳米压痕仪的力-位移曲线显示了关于机械性能更准确和定量的数据。因此，研究人员在为工业应用优化东方漆漆膜的化学成分并改善其物理性能时，会发现我们的方法很有用。
