“…After that, an increase in the concentration of ZnO NPs in EP to 300 and 700 mg/kg has increased the UTS by 45.9 and 48.5%, respectively, as compared to neat EP. This increase in UTS may be attributed to the following mechanism: the fine particles of ZnO were evenly distributed in the EP resin, which makes the load transfer between the nanoparticles and the EP resin equal (Bazrgari et al, 2018;Kameswara Reddy et al, 2020). Additionally, the strong interfacial bonds between the ZnO NPs and the EP resin enhance the mechanical properties by providing an effective load transfer to the nanoparticles, which are more rigid in the EP resin (Ma et al, 2018;Yazman & Samancı, 2019).…”

“…Nonetheless, with a further increase in the concentration of ZnO NPs in EP resin to 800 mg/kg, a decrease of 29.01% in the UTS of the coating, as compared to neat EP, was noticed. This may be attributed to the agglomeration of the ZnO NPs, which then become unevenly distributed in the EP resin (Kameswara Reddy et al, 2020;Wei et al, 2019;M. Wu et al, 2020;Xia et al, 2019).…”

ZnO and ZnAl2O4 nanoparticles (NPs) were successfully prepared by the co-precipitation method and characterized by x-ray powder diffraction, transmission electron microscopy, and Fourier transform infrared spectroscopy. The prepared NPs were incorporated into epoxy (EP) coating with mass ratios 200  800 mg/kg of ZnO NPs/EP and ZnAl2O4 NPs /EP. The prepared coatings were characterized by scanning electron microscopy and Fourier transform infrared spectroscopy, and their mechanical properties were investigated, at room temperature, after 5, 10, 15, and 20 days of preparation. Tensile tests showed an improvement in the tensile properties, with the best improvement in ultimate tensile strength (93.2%) for 800 mg/kg ZnAl2O4 NPs/EP coating after 15 days of preparation. The ZnO NPs/EP and ZnAl2O4 NPs/EP coatings exhibited noticeable sensitivity to the stretching rate. Vickers microhardness (Hv) investigations showed normal indentation size effect behavior for all the samples. The best improvement in Hv was attained after 5 days of preparation, for all coatings, with the best improvement (9.15%) for 700 mg/kg ZnO NPs/EP.

In this study, innovative nanocomposite materials for material extrusion (MEX) 3D printing were developed using a polypropylene (PP) polymer with tungsten carbide (WC) nanopowder. The raw materials were converted into filaments using thermomechanical extrusion. The samples were then fabricated for testing according to the international standards. Extensive mechanical testing was performed on the 3D-printed specimens, including tensile, impact, flexural, and microhardness assessments. In addition, the impact of ceramic additive loading was examined. The thermal and stoichiometric characteristics of the nanocomposites were examined using thermogravimetric analysis, energy-dispersive X-ray spectroscopy, differential scanning calorimetry, and Raman spectroscopy. The 3D-printed shape, quality, and fracture process of the specimens were examined using scanning electron microscopy. The results showed that the filler significantly enhanced the mechanical characteristics of the matrix polymer without reducing its thermal stability or processability. Notably, the highest level of nanocomposite mechanical responsiveness was achieved through the inclusion of 6.0 and 8.0 wt. % fillers. The 10.0 wt. % loading nanocomposite showed significantly increased microhardness, indicating a possible high resistance to wear.

“…Epoxy resins (EP) are the most important polymers, which are widely used in diverse industries spanned from electronic and electrical equipment to civilviation and space parts as surface coatings [1,2] . However, the epoxy resins always mixed with a curing agent, and then under the stimulation of external conditions (such as heating), the active groups of the curing agent react with the epoxy groups on the resin to form a thermosetting material with a three‐dimensional cross‐linked network structure [3] .…”

Curing agents for epoxy resin (EP) are one of the most important branches in the polymer materials field due to their enormous potential in many fields, but constructing them in a well‐controlled curing temperature remains challenging. Herein, a novel curing agent is constructed by the zirconium metal‐organic framework (UiO‐66) and [P4442]2[IDA] through an impregnation method. [P4442]2[IDA]@UiO‐66 is utilized as a functional nanofiller and curing agent to construct the [P4442]2[IDA]@UiO‐66/EP nanocomposites. The chemical structures of [P4442]2[IDA]@UiO‐66 were investigated by XRD, SEM, DSC, and TG characterizations. The various [P4442]2[IDA]@UiO‐66 with different loading amounts of [P4442]2[IDA] were used to investigate the curing behaviors of the EP‐51. The DSC results confirm that the curing temperature of the [P4442]2[IDA]@UiO‐66/EP is higher than that of [P4442]2[IDA]/EP. In addition, the kinetic parameters and the activation energy of the curing reaction were acquired according to the fitting of Kissinger equation and Ozawa equation. The drying time of [P4442]2[IDA]@UiO‐66/EP system at 40 °C was enhanced 17 times compare to that of [P4442]2[IDA]/EP system. This study opens new avenues for the rational design of EP nanocomposites by employing ionic liquids@MOFs composite materials as curing agent for wide engineering applications.
