An overview of possible reproduction processes will be given and a new fabrication route in combination of laser lithography and nickel electroplating to provide stable mold inserts is introduced. Three methods for inspecting the reproduction quality of the polymeric micro-structured surfaces are presented discussing the respective advantages and disadvantages as well as the limiting factors diminishing the resolving power. The replication quality of four micro-structured surfaces produced with the hot embossing method is investigated, and the results are compared using these three techniques. Additionally, the principle investigation strategy of a test rig for droplet impact experiments on micro-structured surfaces is going to be outlined. Finally, preliminary results of droplet impacts on a structured surface are shown and discussed. %@ 978-3-030-33338-6
