Abstract

The aim of this research is to develop a method to prepare a multiferroic-Polyamide 6 (PA6) nanocomposite with tuneable magnetocaloric properties for self-healing structure. It was shown that maintaining the low interaction radius through the dispersion of the low coercivity MNPs, could allow tuning of the bulk magnetocaloric properties of the resulting mesostructures. An in-situ polymerisation method improved dispersion and reduced maximum interaction radius value from ca. 806 to 371 nm as well as increased the magnetic response for silica coated SMNP composite. This sample displayed ca. three orders of magnitude enhancement for magnetic saturation compared to unfunctionalized Fe3O4 MNP composite.
