“…All of these settings prompt the tensile strength of foamed polymeric composites to decrease. The results of this study are supported by Devaraju et al [ 22 ], where an increase in the tensile strength of the test object took place due to the addition of 0.5% wt ZnO NP with an epoxy matrix combined with OPEFB random woven fibers. The specimen with 15% ZnO and 100 mesh size particles was found to have a better stress value than other compositions.…”

The sustainable use of agricultural waste to generate valuable products while minimizing environmental burdens is increasing rapidly. Multiple sources of fibers have been intensively studied concerning their application in various fields and industries. However, few publications have extensively discussed the property’s performance of oil palm empty fruit bunches (OPEFB) composites. With main properties similar to composites currently listed for industrial applications, OPEFB is worth listing as a potential composite for industrial applications and non-structural material alternatives. OPEFB-reinforced polymer composites are expected to be applied to automotive interior parts. This study aims to determine the effect of adding zinc oxide (ZnO) and polyurethane on OPEFB-reinforced polymer composites for automotive interior parts. This composite was produced using the hand lay-up method with 70% resin, 15% OPEFB fiber, 15% polyurethane as a blowing agent, and four variations of ZnO at 5%, 10%, 15%, and 20%. The OPEFB particle sizes are 40, 60, 80, and 100, respectively. The composite was examined to determine mechanical, morphology, chemical, and thermal characteristics. It was observed that the addition of 20% ZnO caused ZnO agglomeration, weakening the interfacial bond between OPEFB particles, polyester, polyurethane, and ZnO filler. Overall, the results showed that adding ZnO and polyurethane to the composite increased tensile, compressive, flexural, and impact strength, as well as thermal stability with more significant values up to 160%, 225%, 100%, 100%, and 4.3%, respectively. This result depicted that the best composition was specimens with 15% ZnO and 149 microns OPEFB fibers particle size. It is considered a promising candidate to be applied in automotive interior components.

Composites made of epoxy‐based systems are popular in many engineering applications because of their enhanced mechanical performance, fatigue properties, and other physical and thermal properties, but their low fracture toughness can limit their usefulness in high‐performance structural applications. This study aims to enhance the fracture properties of epoxy‐based composites by adding cost‐effective ball‐milled graphitic nanoparticles. Herein, dry ball milling for 15 and 48 h is done to produce ball‐milled graphite (BMG) nanoparticles. A significant reduction in particle size is achieved after 15 h of dry milling. Interestingly, a similar reduction in particle size is achieved for BMG (~258 nm) when wet ball milling for 3 h is performed. These BMGs were silanized (SBMG@3) and incorporated into the epoxy network. We found even at a higher loading level of SBMG@3, the resulting nanocomposites exhibited a significant improvement in fracture toughness (~2.47 MPa m1/2) and energy (~1.55 kJ/m2). This improvement was attributed to the upliftment of the in‐plane crack propagation resistance of the nanocomposites primarily offered by SBMG@3 due to coagulated interfacial interaction with the epoxy network that effectively hindered the propagation of the crack by providing numerous sites for energy dissipation, leading to improved fracture toughness. Our results demonstrate that SBMG@3 has great potential for improving the fracture toughness and energy of epoxy‐based composites, making them suitable for various industrial applications.Highlights Synthesized cost‐effective 2D carbon nanofillers via high‐energy ball milling.

KIC and GIC improve to ~2.47 MPa m1/2 and 1.55 kJ/m2, respectively, for ECSB1. FS and FM of the epoxy nanocomposites enhanced by ~43.69% and ~51.64%.

“…Compared to these oxide materials, nanoflakes, nanosheets, and nanowires of WO 3 based polymeric composites were employed efficiently in various usages such as sensitive gas sensors [ 21 , 22 ], dye-sensitized solar cells [ 23 ], lithium-ion batteries [ 24 ], photochromic agents [ 25 ], photocatalytic and antibacterial agents [ 26 , 27 ], supercapacitors [ 28 ], water splitting [ 29 , 30 ], wastewater treatment [ 31 ], dye removal [ 32 ], smart windows [ 33 ], and anticancer agents [ 34 ]. As a result of the properties of zinc oxide, it has appeared a potential interest in the formulation of nano-sized polymeric systems [ 35 ]. Newly, the preparation of convenient components containing ZnO nanoparticles provides effective composites for several implementations such as acetone sensing [ 36 ], photocatalysis [ 37 , 38 ], photodegradation [ 39 ], microbial activity [ 40 ], cancer therapy [ 41 ], and wound dressing [ 42 ], food packaging [ 43 ] and water splitting [ 44 ].…”

Nanoparticles of tungsten oxide (WO3) and zinc oxide (ZnO) enriched polyethylene sebacate (PES) nanocomposites were prepared through the coprecipitation process and condensation polymerization reaction. The obtained nano-sized particles of WO3 and ZnO, PES, and nanocomposites (WO3-PES NC and ZnO-PES NC) were investigated. The average molecular weight of the cured PES was measured by employing the gel permeation chromatography (GPC) technique. Fourier-transform infrared spectroscopy (FTIR) and X-ray diffraction (XRD) spectra assured the formation of the polymeric nanocomposites.WO3 and ZnO nanoparticles supposed a condensed porous spherical phase found implanted in the polymer structure, as detected by scanning electron microscopy (SEM) and transmission electron microscopy (TEM) methods. These nano-scale systems achieved an electrical activity based on the conductive nanoparticles embedded matrix as a result of the ion–ion interactions. The microbial influence of the nanocomposites was examined against pathogenic bacteria; Pseudomonas aeruginosa,Escherichia Coli, Staphylococcus Aureus, and Bacillus subtilis, and Fungi; Aspergillus niger, and Candidaalbicans. Results exhibited that these nanocomposites have antimicrobial effects from moderate to slightly high on bacteria and high on fungi which was confirmed by a clear zone of inhibition. This study contributes to the design of reasonable composites to be under evaluation for their catalytic effect.
