A product, and a method for forming a product, that includes a composite material having a polymeric carrier resin and a shape memory polymer material capable of transformation between a temporary shape and a permanent shape in the presence of an external stimuli, wherein said transformation from said temporary shape to said permanent shape changes at least one property of said composite material.

Microencapsulated chemical(s), as water-soluble solid particles, are embedded in at least one the paint layers on the surface of a magnesium article used in an automobile. If the protective paint film is scratched or otherwise mechanically disturbed to expose the surface of the magnesium article the capsules will be ruptured. This will expose the encapsulated chemical(s) to ambient water enabling them to dissolve and form an aqueous solution capable of reacting with the exposed magnesium to form a protective passivating layer on the exposed magnesium to resist corrosion. In a second embodiment the encapsulated chemicals include a deliquescing compound for extraction of moisture from the atmosphere sufficient to induce dissolution of the passivating layer-forming chemical(s) and trigger the formation of the passivating layer in the absence of ambient water.
摘要:
In an illustrative embodiment, two panels of different materials may be bonded with a structural adhesive composition comprising microcapsules containing corrosion inhibiting materials for protecting the panels from corrosion. For example, a steel vehicle door outer panel may be bonded to an aluminum alloy or magnesium alloy inner panel using an epoxy adhesive. Dispersed within the uncured adhesive are an abundance of microcapsules filled with a fluid or mobile material for reacting with the iron and/or aluminum or magnesium to inhibit corrosion arising from the facing surfaces of the mixed metal panels. The protective material is released from the microcapsules for diffusion through the cured or uncured interfacial adhesive to react with one or both panel surfaces and form a protective coating on the surfaces.
