Abstract: 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.

Abstract: An article comprising a first component having a first electrically conductive surface and a second component having a second surface. An adhesive composition comprising a cured polymerizable ionic liquid is disposed between the first electrically conductive surface and second surface and joins the first component to the second component. The polymerizable ionic liquid comprises an acid functional monomer and the conjugate acid of an imidazole compound. 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.

Abstract: A core-sheath filament having a) a core that is a thermally conductive pressure-sensitive adhesive particles and b) a non-tacky, thermoplastic sheath is provided. The thermally conductive pressure-sensitive adhesive in the core includes a (meth)acrylate-based polymeric material and thermally conductive particles. Additionally, methods of making the core-sheath filament and methods of using the core-sheath filament to print a thermally conductive pressure-sensitive adhesive are described.

Abstract: Optically clear adhesive compositions contain an elastomeric polymer and a low molecular weight polymeric additive. The elastomeric polymer and the low molecular weight polymeric additive form an acid-base interaction. The refractive index of the adhesive composition is higher than the refractive index of the elastomeric polymer. The adhesive composition may also contain additional domains of liquids, polymers, additives or particles that have a higher refractive index than the elastomeric polymer.
