A heat-debondable adhesive article having two opposing sides is provided that includes a shape-memory polymer sheet in its temporary strained shape that includes a plurality of slits therein and a first adhesive on one opposing side of the polymer sheet and a second adhesive on the other opposing side of the polymer sheet. The provided article, optionally, includes a first substrate in contact with the first adhesive and a second substrate in contact with the second adhesive. The article can be debonded by heating the article to a temperature equal to or greater than a transition temperature for the shape-memory polymer sheet.
