Abstract[English]
The present invention relates to a device comprising an electrically modifiable adhesive (A) on an electrically conductive surface (B), such as a backing or substrate. Upon application of an electric stimulus, the device allows stain-free debonding of the adhesive tape from the conductive adherend surface (S). The debonding process leaves the adherend surface undamaged, maintains the original optical and electrical properties of the substrate, thereby, permits use on sensitive adherend surfaces.[French]
La présente invention concerne un dispositif comprenant un adhésif (A) modifiable électriquement sur une surface électriquement conductrice (B), telle qu'un support ou substrat. Lors de l'application d'un stimulus électrique, le dispositif permet un décollement sans tache du ruban adhésif à partir de la surface de support conductrice (S). Le procédé de décollement laisse la surface de support non endommagée, maintient les propriétés optiques et électriques d'origine du substrat, ce qui permet une utilisation sur des surfaces de support sensibles.
