Preparation and Characterization of Non-Stick Surfaces based on PET

The need to develop materials with advanced surface characteristics is becoming increasingly apparent in many fields such as the transport, food and medical industries. In this sense, optimising the use of resources and improving recyclability are imperative to ensure compliance with the objectives of the circular economy. Properties such as non-stick are presented as tools in the development of polymeric surfaces within this new economic model. In this thesis, non-stick surfaces have been prepared by simple, fast and cheap procedures from Polyethylene Terephthalate (PET), one of the most widely used polymers in the world. For this purpose, roughness has been generated by solvent-induced crystallisation and a chemical surface post-treatment with a fluorinated silane has been carried out.
