“…Increasing the concentration of nanoparticles positively affects the mechanical properties of the samples and significantly reduces the effect of the temperature increase on the tensile parameters. The improvement in mechanical properties by the addition of nanoparticles has also been reported by other researchers [ 24 , 25 , 26 ]. At a certain temperature, with increasing nanoparticle concentration, tensile properties such as strength, elongation at break, and modulus increase.…”

In this study, the effects of NBR polarity and organoclay addition on the curing, rheological, mechanical, and thermal properties of an NBR/phenolic resin blend were investigated. The samples were prepared using a two-roll mill. The results showed that rheological and tensile properties improved due to the good distribution of nanoparticles, as well as the good compatibility of nitrile butadiene rubber with phenolic resin. The addition of 1.5 phr of nanoparticles to blends containing 33% and 45% acrylonitrile increased the curing torque difference by approximately 12% and 28%, respectively. In addition, the scorch time and curing time decreased in nanocomposites. Adding nanoparticles also increased the viscosity. The addition of phenolic resins and nanoparticles has a similar trend in modulus changes, and both of these factors increase the stiffness and, consequently, the elastic and viscous modulus of the specimens. Adding 1.5 phr of organoclay increased the tensile strength of the blends by around 8% and 13% in the samples with low and high content of acrylonitrile, respectively. Increasing the temperature of the tensile test led to a reduction in the tensile properties of the samples. Tensile strength, elongation at break, modulus, and hardness of the samples increased with increasing organoclay content. In addition, with increasing nanoparticle concentration, the samples underwent lower deterioration in tensile strength and Young’s modulus at different temperatures compared to the blends. In the samples containing 1.5 phr of organoclay, the thermal decomposition temperatures were enhanced by around 24 and 27 °C for low and high acrylonitrile content.

“…This can be attributed to the greater hardness of BS compared to pristine PF. When an external force is applied to composite samples, BS plays the most important role in tolerating and diverting the force, thereby increasing the hardness of the PF/H‐BS composites 4,41 …”

“…It is widely used in construction, transportation, electronics, and aerospace because of its low cost, simple molding process, excellent mechanical properties, and heat resistance. [1][2][3][4] However, PF exhibits high brittleness and low-impact strength due to the closely packed rigid aromatic rings attached to the methylene groups during the curing process. Moreover, PF has relatively low-thermal stability because of the presence of phenolic hydroxyl and methylene groups.…”

In this study, phenolic formaldehyde (PF) resin-based composites were prepared using basalt scale (BS) as a reinforcing agent via a melting-blending method. The BS surface was treated with hydrochloric acid, and the surface properties were characterized using thermal field-emission scanning electron microscopy, Fourier-transform infrared, X-ray photoelectron spectrometry, and energy-dispersive X-ray spectroscopy. Moreover, the influence of acidtreated BS (H-BS) content on the thermal properties, flexural properties, impact strength, and morphology of PF/H-BS composites was investigated. The thermal stability and glass transition temperature of the composites increased significantly with the increasing H-BS content. The impact strength tests indicated that the impact strength of the composite with 15 wt% H-BS was 0.66 kJ/m 2 , which is 153% higher than that of pristine PF. The scanning electron microscopy results indicated that the PF/H-BS composites exhibit rough morphology with numerous microcracks.

“…The prepared composite had the highest activity with 96% photodegradation efficiency. In another study, both hydrothermal and microemulsion synthesis methods were applied to prepare zinc oxide/activated carbon nanocomposites with controlled particle size and even distribution [46][47][48]. A microemulsion of an oleic acid/n-Butanol/ sodium hydroxide solution was utilized as a precursor for preparing zinc oxide/activated carbon composites.…”

Zinc oxide (ZnO) is used for various purposes because of its special physico-chemical properties, including large band gap, high binding energy of exciton, nontoxicity, high chemical and thermal stability, large piezoelectric constants, and wurtzite crystal structure with various and widespread applications in electronics, optoelectronics, biochemical sensing, biomedical, and energy-saving systems. This review mainly aimed to present the recent improvement in ZnO-based composite materials with utilization in energy storage systems with a specific focus on lithium-ion batteries, dye-sensitized solar cells, and supercapacitors. The first part of this paper looks at the structure and properties of ZnO and then describes some of the most common synthesizing methods of ZnO composites, including electrochemical, chemical, solvo/hydrothermal, and physical deposition methods. Finally, the recent advancement of ZnO-based composite materials applied in energy storage systems was discussed.
