Articles containing adhesive compositions exhibiting on-demand debonding behavior

An article comprising:

• a first component having a first electrically conductive surface;
• a second component having a second surface;
• and
• an adhesive composition disposed between the first electrically conductive surface and the second surface, the adhesive composition comprising a zwitterionic polymer,
• wherein the adhesive composition joins the first component to the second component, and
• wherein the effort required to separate the first component from the second component, as measured by work of adhesion per surface area, is reduced by application of a DC electric potential across the adhesive composition;
• and
• wherein the zwitterionic polymer consists essentially of the polymerized product of:
• a. 0.2 wt % to 16 wt %, based on the total weight of polymer, of anionic monomers comprising acrylic acid, methacrylic acid, a carboxylate salt thereof, or a mixture of two or more thereof, wherein the amount of carboxylate salt is based on the weight of the corresponding free acid;
• b. 2 wt % to 25 wt %, based on the total weight of polymer, of one or more cationic monomers comprising an acrylate or a methacrylate ester having alkylammonium functionality;
• c. 50 wt % to 95 wt %, based on the total weight of polymer, of one or more nonionic monomers comprising an acrylate or a methacrylate ester of an alcohol having between 2 and 18 carbons;
• and
• d. 0 wt % to 40 wt %, based on the total weight of polymer, of more or more additional monomers.
