“…No literature is yet available on HDPE 3D Printed nanocomposites with which to correlate these mechanical findings. Research showed that there are a few publications available, but they are on injection-molded specimens [36,37], and they do not report any findings on mechanical properties with which to correlate the above findings of this work regarding the mechanical response of the nanocomposites. It should be noted that the tensile and the flexural tests do not follow the same trend regarding the mechanical test results as the filler loading increases.…”

“…Literature includes HDPE with the addition of carbon nanotubes [24], fly ash cenospheres [25][26][27], glass micro balloons [28][29][30], carbon [31], calcium carbonate [32], and graphite nanofibers [33]. Moreover, literature reports that quantity-wise, HDPE with nanofillers in concentrations below 5 wt.% can significantly improve the mechanical strength of the HDPE matrix when used in 3D printing [34][35][36].…”

“…Moreover, research was done in literature on HDPE and its electrical and thermal properties and how they change when nano or micro fillers are added. Literature contains reports with HDPE doped with Titanium Dioxide (TiO 2 ) [36][37][38], Tin Oxide (SnO 2 ) [35][36][37][38][39], alumina [40,41], and Zinc Oxide (ZnO) [42]. All the above research was done upon injection molded specimens or machined specimens from bulk materials.…”

Aiming to develop more robust, mechanically advanced, Fused Filament Fabrication (FFF) materials, High-Density Polyethylene (HDPE) nanocomposites were developed in the current research work. Titanium Dioxide (TiO2) was selected as filler to be incorporated into the HDPE matrix in concentration steps of 0.5, 2.5, 5, and 10 wt.%. 3D printing nanocomposite filaments were extruded in ~1.75 mm diameter and used to 3D print and test tensile and flexion specimens according to international standards. Reported results indicate that the filler contributes to increasing the mechanical strength of the virgin HDPE at certain filler and filler type concentrations; with the highest values reported to be 37.8% higher in tensile strength with HDPE/TiO2 10 wt.%. Morphological and thermal characterization was performed utilizing Scanning Electron Microscopy (SEM), Raman, Thermogravimetric Analysis (TGA), and Differential Scanning Calorimetry (DSC), while the results were correlated with the available literature.

“…However, the low dielectric constant (< 3) of them considerably limits their applications. Substrates with higher dielectric constant possess smaller dimension, which helps to meet the requirement of circuit miniaturization and expand their application scopes . Hence, it is of great significance to increase the dielectric constant of the polyolefin resins while maintaining other excellent properties.…”

Fibre-reinforced polybutadiene/ styrene-butadiene-styrene triblock copolymer/ ethylene-propylene-diene terpolymer/titanium dioxide (PB/SBS/EPDM/TiO 2 ) composite laminates with superior dielectric properties were fabricated by impregnation and hot pressing. The effects of concentration and particle size of rutile spherical TiO 2 on the microwave dielectric properties of the PB/SBS/EPDM/TiO 2 composite laminates were investigated at microwave frequency region. Additionally, the mechanical, thermal, and water absorption properties of the laminates were also evaluated. Results indicated that the dielectric properties were obviously improved with the increase of concentration or the decrease of particle size. The laminate filled with 230 nm TiO 2 at a filler loading of 70 wt% possessed high dielectric constant (7.03, 10 GHz), low dielectric loss (0.0042, 10 GHz), outstanding mechanical, thermal properties, and low water absorption. Enhanced dielectric properties and other prominent properties enable the fibre-reinforced polyolefin-based composite laminates to be a potential candidate for microwave substrate applications.
