Nature provides us with a large number of biological surfaces with multifunctional properties. An example is the lotus leaf, which has numerous functionalities, such as superhydrophobicity and self-cleaning. Numerous studies have shown that the lotus leaf contains a hierarchical structure that contains a major micro-scale structure in the range of 10-50 microns and a minor structure in the range of 200 nm - 2 μm. In the last decades, research has been carried out on the manufacture and characterization of artificially textured surfaces mimicking the structure of the lotus leaf. At IQS he is investigating the production of superhydrophobic textures by plastic injection from a nanotextured mold by laser. The nanometric motifs are replicated on the mold by microinjection. In this Final Degree Project, the roughness of the hierarchical surfaces of the injection mold is characterized and the influence of the mold temperature on the replication of these superhydrophobic structures on propylene pieces is studied.
