Morphological, mechanical, magnetic, and thermal properties of 3D printed functional polymeric structures modified with Fe₂O₃ nanoparticles

Abstract

The Fe 2 O 3 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 Fe 2 O 3 nanoparticles. Nanocomposite structures are successfully produced in the desired complexity with the additive manufacturing method. In the current study, Fe 2 O 3 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 Fe 2 O 3 nanoparticles improved the thermal stability of the structures.Moreover, an increase in magnetic properties has been observed up to 459%.

Enhancing the tensile properties of PA6/CNT nanocomposite in selective laser sintering process

“…The mechanical and thermal properties of PA6/clay nanocomposite fabricated with SLS process were studied by Kim and Creasy, [21] who reported that clay nanoparticles increased the viscosity and mechanical properties of the nanocomposite. Analysis of the mechanical properties of nanocomposites produced by 3D printing has been also studied by Guaricela et al [22] and Aktitiz et al [23,24] A review of previous works on the polymer nanocomposites indicated that enhancement of the mechanical properties of nanocomposites fabricated by the SLS process has been recently came into consideration. However, the SLS process has not been used to produce PA6/CNT nanocomposite.…”
