Fe2O3 nanoparticle structures are extensively studied in various application areas due to the compatibility between organic polymers and inorganic Fe2O3 nanoparticles. Nanocomposite structures with desired complexity can be successfully produced using additive manufacturing methods. In this study, Fe2O3 nanoparticles were doped into photocurable resin at different concentrations and printed using stereolithography. The morphological, mechanical, magnetic, and thermal properties of the printed nanocomposites were investigated, and it was found that Fe2O3 nanoparticles improved thermal stability and magnetic properties significantly.
The Fe2O3 nanoparticle structures, which have many application areas such as electronics, marine, and aviation, have been studying extensively due to the compliance between organic polymer and inorganic Fe2O3 nanoparticles. Nanocomposite structures are successfully produced in the desired complexity with the additive manufacturing method. In the current study, Fe2O3 nanoparticles were doped into the photocurable resin at different concentrations (pristine, 0.25%, 0.5%, and 1% in wt), and the prepared 3D polymer nanocomposite mixtures were printed via stereolithography method. To investigate the morphological, mechanical, magnetic, and thermal properties of the printed nanocomposite structures, scanning electron microscopy, hardness, vibrating sample magnetometer, thermogravimetric analysis, and differential scanning calorimeter analysis were performed, respectively. It was revealed that the Fe2O3 nanoparticles improved the thermal stability of the structures. Moreover, an increase in magnetic properties has been observed up to 459%.
