Abstract

Surface energy calculation of materials in production technology has become even more important in terms of surface quality with interfacial phenomena. In this study, geometric-harmonic mean equation, OWRK, Schultz and Dorris–Gray methods were applied to characterize surface energy of paragonite mica by contact angle measurement technique (CAMT) and inverse gas chromatography (IGC) at room temperature. Total energy ranges from 49 to 122 mN/m. While values obtained from Dorris–Gray and Schultz methods are higher than others, the dispersive component result of Dorris–Gray is slightly higher than Schultz method. This work clearly shows that the surface energy of even superhydrophilic surfaces can be calculated by both CAMT and IGC. However, it was obtained with a comparative study that IGC with Dorris–Gray method is a well beneficial measurement tool to calculate surface energy.

文石云母表面能表征的比较研究

摘要

在具有界面现象的表面质量方面，生产技术中材料的表面能计算变得更加重要。在这项研究中，采用几何调和平均方程、OWRK、Schultz 和 Dorris-Gray 方法通过接触角测量技术 (CAMT) 和反气相色谱 (IGC) 在室温下表征了菱沸石云母的表面能。总能量范围为 49 至 122 mN/m。虽然从 Dorris-Gray 和 Schultz 方法获得的值高于其他方法，但 Dorris-Gray 的色散分量结果略高于 Schultz 方法。这项工作清楚地表明，即使是超亲水表面的表面能也可以通过 CAMT 和 IGC 计算。然而，
