METHOD FOR MEASURING THE TOPOGRAPHY AND SURFACE ENERGY OF A SURFACE OF A SOLID SAMPLE BY CONFOCAL MICROSCOPE AND DEVICE FOR CARRYING IT OUT

摘要

Method for measuring the topography and surface energy of a surface of a solid sample (101), comprising the steps consisting of:a) positioning the sample (101) on a sample-holder stage (102) of a confocal device (103);b) determining a measurement area (204) in the sample (101);c) determining the topography of the measurement area (204) by means of confocal microscopy;d) placing a drop (301) in the measurement area (204);e) determining the contact angle ϑ of the drop (301);f) determining the coordinates of the edges of the contact surface between the drop (301) and the sample (101);g) selecting from the subset of the topography corresponding to the edges of the contact surface between the drop (301) and the sample (101);h) determining the surface energy of the solid (γ_s), based on the topographical data of the subset and the contact angle of the drop (301).
