Adhesion between NiTi shape memory alloy and thermoplastic polymers — •Klaus Neuking, Stephane Youcheu Kemtchou, Anwar Abu-Zarifa, and Gunther Eggeler — Ruhr-Universität Bochum, Werkstoffwissenschaft

NiTi has a particular technical importance due to its good shape memory properties. To increase the engineering potential, the combination with polymers is particularly interesting. One method to improve the poor bonding between metal and polymer is to deposit a thin interlayer which acts as a coupling agent between the two components. In this study the influence of silanisation on the adhesion to polyamid 6 and thermoplastic polyurethane has been investigated. The NiTi-surface was characterised with XPS and AFM to identify the oxide types and the morphology. The coated material was investigated with FT-IR spectroscopy and spectroscopic ellipsometry. Additionally pull-out tests were made to show the effect of the silanisation on the adhesion.
