摘要： 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.

摘要： A polymerizable composition includes at least one monomer, a photoinitiator capable of initiating polymerization of the monomer when exposed to light, and a phosphor capable of producing light when exposed to radiation (typically X-rays). The material is particularly suitable for bonding components at ambient temperature in situations where the bond joint is not accessible to an external light source. An associated method includes: placing a polymerizable adhesive composition, including a photoinitiator and energy converting material, such as a down-converting phosphor, in contact with at least two components to be bonded to form an assembly; and, irradiating the assembly with radiation at a first wavelength, capable of conversion (down-conversion by the phosphor) to a second wavelength capable of activating the photoinitiator, to prepare items such as inkjet cartridges, wafer-to-wafer assemblies, semiconductors, integrated circuits, and the like.

摘要： The subject invention pertains to a method of forming an adhesive material by a branching polymerization free of restrictive or harsh reaction conditions. A readily polymerizable composition includes a component comprises a chain-transfer functionality that can induce the formation of branches upon polymerization of the composition.
