Abstract
This thesis reviews the needs of the research and industry for surface wetting characterization, as well as the different wetting characterization methods available. The thesis puts in evidence the arising need for a method of fast surface wetting scanning. The Scanning Droplet Tribometer (SDT) offers a solution to this need. This instrument scans the friction and adhesion forces of a magnetically controlled water-like droplet on a surface. However, the original design of the SDT requires further development. The sources of errors are investigated, and we suggest improvements to the SDT, to make it more reliable and adapted to a wider range of samples.
