| Résumé : |
In this study, OW · WO emulsions, which are similar to the product formulation, were used for thin film deposition at high speeds. The evaluation of the developed thin films showed that the shear process during the application of OW emulsions caused coalescence deformation, which was related to the nonuniformity of the properties of the applied films. In contrast, the WO emulsion, which did not deform on the shear surface, formed a uniform coating film under all conditions from coating to drying. Therefore, it is important to determine a rheological measurement method to predict the unification processes of a product design that considers the coating properties. |
