    Abstract: Provided are adhesive articles and related methods of making and use. The adhesive article includes one or more patterned adhesive layers comprising compositionally and spatially distinct adhesives that are laterally disposed relative to each other. The first and second adhesives are optionally capable of being functionally cured to provide a structural adhesive bond with a substrate. These adhesives can provide high fracture toughness and high modulus characteristics not otherwise possible in a homogeneous adhesive composition. These adhesives can provide some degree of crack arrestment and significantly reduce the need for mechanical fasteners in industrial bonding applications.

    Abstract: Provided is a curable composition containing a reactive mixture of components including an polyethersulfone having a chemical group reactive with an epoxide, a cycloaliphatic polyepoxide resin, a polyepoxide having a functionality greater than two, a liquid diepoxide resin, a first curative containing 9,9-bis(aminophenyl)fluorene or a derivative therefrom and having a curing onset temperature of from 150° C. to 200° C. The components can further comprise a second curative having a curing onset temperature of from 60° C. to 180° C. When thermally curing this composition, the second epoxy curative starts to cure before the first epoxy curative, thereby inhibiting vertical flow of the adhesive during the curing process.

    Abstract: A method is provided for making structured hybrid adhesive articles comprising the steps of: a) providing an adhesive article comprising: i) a base resin comprising an epoxy resin, ii) a first epoxy curative, and iii) a second epoxy curative, by reacting the base resin with the first epoxy curative such that the first epoxy curative is substantially reacted with epoxy resin in the article and the second epoxy curative is substantially unreacted in the article; b) embossing the adhesive article with a relief pattern; and c) curing the adhesive article such that the second epoxy curative is substantially reacted with epoxy in the article. In some embodiments, the method additionally comprises a step of embedding a scrim in the adhesive. In some embodiments, the method additionally comprises a step of depositing an electrically conductive layer onto the surface of the adhesive article embossed with the relief pattern.
