In this work, metallic tools are surface modified with different perfluoroalkylsilanes from the liquid phase. In particular, these molecular coatings are investigated with respect to their anti-adhesive properties, durability and long-term stability. Steel surfaces are treated with acid (dilute HNO3) to increase the density of surface hydroxyl group. The modification of the metal surface is achieved by subsequent reaction of the surface hydroxyl groups with organo-silanes. The characterization of the modified surfaces is performed by X-ray photoelectron spectroscopy (XPS), and contact angle measurements. The work aims at strategies to reduce demolding forces in injection molding processes.
