New publication on the Adhesion Engineering in Polymer–Metal Comolded Joints with Biomimetic Polydopamine

Giorgos Kafkopoulos published his paper titled: Adhesion Engineering in Polymer–Metal Comolded Joints with Biomimetic Polydopamine. The work has been performed within the NWO funded ECOMOLD project, in collaboration with the University of Twente, in which Giorgos and TPRC researcher Vanessa Marinosci study the correlation between mechanical performance and titanium surface morphology of co-consolidated Ti6Al4V-C/PEKK joints.

Joining co-molded metals and thermoplastic polymers carries a great significance for a number of industrial applications, from electronics to automotive and aerospace. Using a model system that exhibits poor interfacial adhesion (i.e. PMMA and Titanium grade 5), Giorgos shows how novel surface treatments using adhesion promoting layers can result in strong bonding in polymer-metal systems. The results of this study not only provide insights into the failure mechanisms of polymer metal joints but also suggest that novel surface modification strategies based on polydopamine carry a high potential for future co-molding applications.
