“…These composites are made of the mixture of fibers, wood particles and other lignocellulosic materials, such as wheat stalks and straw, canola, rice, and melted jute with thermoplastic polymers (plastic) (Klyosov, 2006;Ismaeilimoghadam et al, 2016). Wood fiber plastic composites (WFPC) are mixtures of polymer and cellulose materials (Samariha et al, 2013;Kiaei et al, 2017a;Kiaei et al, 2017b). The addition of fibers and natural fillers to reduce costs in the plastic industry and sometimes increase the production have drawn attention after relatively increased plastic costs in previous years.…”

HIGHLIGHTSThe results showed that the addition of nanosilica increased the thermal stability of the nanocomposite.It was determined that increasing of nano particles to more than a determined level reduced the Limited oxigen index and flammability.The data from thermo gravimetric analysis (TGA) indicated the nanosilica greatly enhanced the thermal stability. ABSTRACTThe present study considered the effect of nanosilica levels on the thermal, flammability, and morphological properties of nanocomposites made of wood flour and recycled polystyrene. To do so, the recycled polystyrene (50%), wood flour (50%), nanosilica (four levels of nanosilica; 0, 2, 4 and 6 phc (parts per hundred compounds)), and maleic anhydride, grafted with polypropylene (at a constant level of 3 phc) were mixed by a twin-screw extruder; then standard experimental samples were made using a hand pressing method. Next, the thermal and flammability properties were measured. The results showed that increasing of nanosilica content to 6 phc by weight increased thermogravimetric analysis (TGA) of nanocomposites; in addition, the limited oxygen index increased. Moreover, scanning electron microscopy (SEM) indicated that an increasing of nanosilica increased compatibility so that better link and adherence was observed among the fiber and matrix material.

“…To explain this trend, according to the research by Kiaei et al (2017), agglomeration in the composite system and the weak interfacial interaction between the nanoparticles and polymer matrix at a higher filler loading should be noted. [ 25 ]…”

“…The flexural strength and modulus of the samples reinforced with nanofillers were found to be higher than the samples without nanoparticles. [ 25 ] Alsayed et al (2020) prepared HDPE/ZnO composites using the compression molding technique by adding both nano and bulk ZnO as a function of nanofillers. Compared to pure HDPE, Young's modulus, ultimate tensile strength, and yield stress of the composites were improved at 10 and 20 wt%.…”

High‐density polyethylene/zinc oxide nanocomposite with antibacterial and anti‐UV radiation properties to reduce evaporation from free surface waters

Climate change, through rising temperatures, higher evaporation rates, and changes in rainfall, can significantly affect the availability of water resources. Evaporation losses from open‐air reservoirs can exacerbate the problem of water scarcity, making it difficult to conserve water. Accordingly, this research aimed to develop nano‐reinforced floating covers to reduce evaporation from free water surfaces. For this purpose, high‐density polyethylene (HDPE), and zinc oxide (ZnO) nanoparticles, via melt‐blending procedures, were used to fabricate the nanocomposites. The morphological, mechanical, antibacterial, and photo‐degradation responses of HDPE/ZnO nanocomposites were assessed, and the physicochemical parameters of water samples were also examined to ensure that nanocomposites did not negatively affect water quality. The results indicated that adding 1 wt% nanofiller increased the tensile strength, while flexural strength values were modestly improved by increasing nanofillers up to 10 wt%. The irradiated nanocomposites generally displayed significant enhancement not only in the tensile strength but also in the flexural strength. Meanwhile, the addition of ZnO to HDPE had no adverse effects on water quality, though contributing to the antibacterial performance of the specimens over the neat polymer. To conclude, the fabricated nanocomposite with 1 wt% ZnO could be proposed as a promising candidate to reduce evaporation losses from free water surfaces, especially in arid and semi‐arid areas.

“…[34][35][36][37][38] Numerous innovative research has concentrated on the incorporation of both MgO NPs and ZnO NPs in several polymeric matrices. 39,40 Kiaei et al 41 researched the incorporation of the latter in wood flour/HDPE composites and noted that as the amount of ZnO increased, so did its flexural strength and modulus. On the other hand, there was a noticeable decrease in these composites burning rate and the amount of heat they released.…”

Polymer nanocomposites have placed themselves in a highly favorable position in use in practical applications, with materials currently employed in technology related processes. This is because they have improved chemical, physical, morphological, structural, and mechanical properties compared to their polymer microcomposites counterparts or even neat polymer. In this study, two inorganic nanofillers, namely magnesium oxide nanoparticles (MgO NPs) and zinc oxide nanoparticles (ZnO NPs) were separately incorporated into high-density polyethylene (HDPE) by melt blending technique. The ZnO NPs contents in the nanocomposites were set at 1.0, 2.0, 4.0, and 6.0 wt%, while 2.0, 4.0, 6.0, and 8.0 wt % were used by MgO NPs. A comparative study was conducted between different features of the nanocomposites based on their compositions. Such features included mechanical properties, thermal stability, morphological, and structural properties. The as-prepared nanocomposites were proven to be crystalline as confirmed from the XRD. Based on the SEM, both nanofillers were found homogenously dispersed in the HDPE matrix. DSC confirmed that the melting and crystallization behaviors of all nanocomposites were not significantly influenced by the addition of the nanofillers. Tensile tests were performed to determine elastic modulus, tensile stress at yield, tensile stress at break, along with tensile strain at yield values and tensile strain at break. The collected results revealed that loading 2.0 wt% ZnO NPs in the nanocomposites provided elastic modulus up to 237% compared to the pure HDPE. In the case of MgO NPs, as their loading in the nanocomposites reached 4.0 wt%, the elastic modulus increased to 160%. The tensile stress of synthesized nanocomposites increased up to 35.95 ± 2.09 MPa using 2.0 wt% ZnO NPs-filled nanocomposites and up to 28.15 ± 0.91 using 4.0 wt% MgO NPs. Overall, the 2.0 wt% ZnO/HDPE nanocomposite presented better mechanical characteristics in comparison to other tested nanocomposites in this study.
