Abstract
A method for curing a macromolecular cyanurate network. The method of curing includes suspending a plurality of functionalized silica-coated magnetic nanoparticles in a resin mixture, which includes cyanate ester monomers, cyanate ester oligomers, or both. After a static magnetic field is applied to the plurality of functionalized silica-coated magnetic nanoparticles in the resin mixture, an alternating electromagnetic field (having frequency ranging from about 1 kHz to about 10 MHz) is imposed for a cure time.
