Synthesis of polyoxometalate-loaded epoxy composites

DWPI Title: Manufacture of polyoxometalate-loaded epoxy used for e.g. epoxy coating, involves adding polyoxometalate to epoxy resin, applying external stimulus for releasing acid from polyoxometalate, and catalyzing cure reaction of resin
Abstract: The synthesis of a polyoxometalate-loaded epoxy uses a one-step cure by applying an external stimulus to release the acid from the polyoxometalate and thereby catalyze the cure reaction of the epoxy resin. Such polyoxometalate-loaded epoxy composites afford the cured epoxy unique properties imparted by the intrinsic properties of the polyoxometalate. For example, polyoxometalate-loaded epoxy composites can be used as corrosion resistant epoxy coatings, for encapsulation of electronics with improved dielectric properties, and for structural applications with improved mechanical properties.
Use: Manufacture of polyoxometalate-loaded epoxy used in epoxy coating, encapsulation of electronics, automotive, medical, aerospace, construction and structural applications.
Advantage: The method produces polyoxometalate-loaded epoxy having excellent mechanical property, and dielectric property. The polyoxometalate-loaded epoxy provides the epoxy coating having excellent corrosion resistance.
Novelty: A polyoxometalate is added to an epoxy resin, comprising heteropoly acid having Dawson structure (I). An external stimulus is applied to release acid from the polyoxometalate. Cure reaction of the epoxy resin is catalyzed, to obtain polyoxometalate-loaded epoxy.
