摘要： The invention relates to the reversible separation of adhesive bonded composites by applying electromagnetic alternating fields. The adhesive bonded composite comprises at least one primer coating which contains nanoscale sized particles having ferromagnetic, ferrimagnetic, superparamagnetic or piezoelectric characteristics. Large amounts of heat are generated locally in the primer coat pertaining to the adhesive bonded composites by applying electromagnetic alternating fields. Such local heat generation in bordering thermoplastic adhesive layers causes a softening of the thermoplastic binding agent. If duroplastic adhesives border on the boundary layer to the then the large amount of local heat generated causes a resplitting of the cross-linked structure of the binding agent matrix. In both cases strong local heating of the boundary layer enables quasi-adhesive substrate separation at low energy inputs.
