Production of different metal oxide nanoparticle embedded polymer matrix composite structures by the additive manufacturing technology and investigation of their properties

Abstract

Metal oxide nano additives are widely used as a second phase modifier as they improve the properties of the matrix materials. Nano additives also supply various advantages for polymers which can be employed in additive manufacturing methods. Among the additive manufacturing methods, stereolithography is one of the most remarkable to produce nano-modified polymers because of the easy nano modification of the photocurable resins. In the present study, we mixed the metal oxide particles; Fe 2 O 3 , ZnO, NiO, Al 2 O 3 , TiO 2 , and MgO with the photocurable epoxy and used the mixtures to print the specimens. We investigated the structural morphology, thermal and mechanical properties of the printed specimens with an optical microscope, scanning electron microscope, Fourier transform infrared spectroscopy, differential scanning calorimeter, differential thermogravimetric analysis, and microhardness, respectively. Findings proved the dilute agglomeration of the nano additives. Besides, nano additives can improve the thermal stability of the photo-cured polymer. The microhardness of the Fe 2 O 3 added polymers reached 27.63 HV levels while it was measured as 16.16 HV for the pristine samples (~70% raise was experienced). The maximum degradation temperatures of the polymer nanocomposite structures were measured in the range of 396-420 C.

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.…”

Recent Advances in the Development of Lipid-, Metal-, Carbon-, and Polymer-Based Nanomaterials for Antibacterial Applications

“…Fine dispersions of metal oxide nanoparticles can be achieved by forming polymer-matrix metal oxide nanocomposites in a manufacturing process similar to polymer-matrix metal nanocomposites. There is an increasing interest in using metal oxide nanoparticles to replace metal nanoparticles for synthesizing polymer-matrix metal oxide nanocomposites [ 240 , 241 , 242 , 243 ]. Metal oxide nanoparticles, especially zinc oxide nanoparticles, are more desirable than metal nanoparticles as nanofillers in forming polymer-matrix nanocomposites [ 244 , 245 , 246 , 247 ].…”
