Who does not love epoxy? Epoxy resins, also known as polyepoxides, are an important adhesive in many applications, both industrial and on a smaller scale. However, many polyepoxides require the application of heat (around 150 ° C for most types) to cure (cure), which can be complicated when the resin is applied or inside layers of temperature sensitive materials. Now, researchers at Nanyang Technological University (NTU) in Singapore have found a way to heat resins using an alternating magnetic field (PDF), so-called magnetic curing.
As described in the research article by R. Chaudhary et al., They used commercially available epoxy resins and added nanoparticles of a MnxZn1
After trying a number of different alloy formulations, they settled on Mn0.7Zn0.3Fairy2O4 as the optimal formulation where no resin combustion occurred. As with all research, it is difficult to say when (and if) it will turn it into commercial applications, but if this type of technology works out, we can soon glue parts together using epoxy resin and an EM field instead of fumbling. with the pleasure of two-component epoxy.
