Abstract

Femtosecond laser surface patterning is a powerful tool capable of producing hierarchical surface features with possible applications in various scientific and industrial fields. In this work, we investigate several piratical aspects of this technology. Contact angle modification for several various materials is investigated, highlighting how it can be changed from superhydrophobic to superhydrophobic. This is followed up by an inquiry into the possibility to use laser patterned surfaces for friction control. Finally, we investigate the influence of chemical polishing on surface chemistry and topography. It is relevant for possible uses in medicine. Overall, shown results give important insights into the practical implementation aspect of the produced surface patterns.
