Magnetic nanoparticles can be dispersed within thermally activated epoxy resins to cure the resin by exposing the fluid to an alternating magnetic field, causing the nanoparticles within to generate heat and cure the epoxy. This magnetocuring method is currently being studied due to its ability to deliver rapid, localised heating and on-demand activation, which are useful characteristics for commercial adhesives. In this paper, a series of structure-property relationships are established for MnZn Fe nanoparticles with the aim to predict the temperatures they can reach by adjusting the various parameters. Temperatures can overlap the activation temperatures of different initiators for thermoset curing and processing temperature of thermoplastic. This report will focus on the geometry and type of container holding the fluid, the strength of the alternating magnetic field and the concentration of nanoparticle in the fluid. Heat generation capabilities would then be assessed by calculating the Specific Absorption Rate (SAR) from the temperature curves obtained. This study aims to provide correlations across different parameters and the SAR so that we can better understand how to control SAR by adjusting parameters in future studies.
