Induction heating is widely employed for the heating and bonding of metals. In principle an alternating electromagnetic field induces an Eddy current in a susceptor, often a metal, which delivers energy in form of heat to the surrounding medium.[1] Our aim is to apply the macroscopic principle to the nanoscopic area and interfacial bonding of polymer materials. Using metal susceptors for targeted heating the interphase of reactive polymer materials, that induces covalent bond formation between Bisphenol-A based Polycarbonate (PC) and Polyvinylamine. Previous works showed that high magnetic field induction is a suited technique for the reactive bonding between these polymers using silver structures as susceptor.[2] In our approach silver was replaced by gold due to avoid the energy loss which is caused by rapid silver oxidation. The second requirement for especially interfacial induced heating is the application of ultra-thin metallic structures in order to reduce the heating of the bulk material. Thus, stable gold structures were produced by different methods: evaporation and sputtering. These gold structures have been morphologically and electrically characterized. The comparison of both preparation methods was performed to optimize the susceptor structures regarding their heating efficiency. FTIR spectroscopic Imaging was applied to investigate the covalent bond formation between PC and Octadecylamine as result of interfacial heating effect. [1] J. Chovan, M.
