We prepared microwave-responsive “on-demand-peeling” adhesives simply by mixing second-generation acrylic adhesives with ionic liquids. A rapid response (<30 s for adhesive failure) to microwave irradiation was achieved using a microwave oven. This “on-demand-peeling” was attributed to local heating of the ionic liquid in the adhesive by microwave irradiation. In addition, the adhesive strength was not influenced by the ionic liquid additives without microwave irradiation. We revealed that the local heating and the plasticizing effect of the ionic liquid were the cause of the “on-demand-peeling”. Our preparation method for these microwave-responsive adhesives is simple, conventional, and attractive for the fundamental and industrial fields.
