A Comparative Study of Surface Energy Characterization for Paragonite Mica

OpenAlex İngilizce

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.
