“…Specifically, the valorization of polymers for producing new sustainable products is developed. Combination of waste, low-carbon, low-energy, and natural byproducts for making polymeric and nonpolymeric composites can provide specific advantages. − Polymers have numerous superior properties compared with other materials, so the ability to exploit their waste in developing materials and new products was discussed. − The thermoplastic polymers serve as promising materials owing to their good mechanical and physical properties. Types of thermoplastics, such as polyethylene terephthalate (PET), polyethylene (PE), polyvinyl chloride (PVC), poly(methyl methacrylate) (PMMA), and others, are recently applied with different forms in the fields of composites, pipelines, electronics, aerospace, food and water packaging, microfluidics, optical materials, etc. − PVC and PET are widely used thermoplastic polymers and have daily multipurpose applications.…”

The hazards of polymer waste and emitted gas on the environment pose a global challenge. As a trial to control this, the current work aims to reuse the polymer waste mix (PM) as fillers in calcium silicate to prepare new composites of environmentally friendly polymer concrete. PM was first subjected to treatment to obtain treated PM (TPM) and then was filled in new dicalcium silicate cement with different concentrations. The microstructural characterizations declare the successful preparation of the dicalcium silicate base material. After the curing reaction, the precipitated carbonate main product is responsible for the gained properties. The CO 2 uptake% in the proposed composites reached 16.6%, referring to the successful storage of CO 2 gas during curing. The treatment reaction led to an increase in the flexural and compression strengths due to the strengthening of the polymer waste mix−cement interface; the strengths were increased gradually with more contents of TPM fillers. 7% TPM−cement concentration achieved the highest flexural strength and compression strength of10.2 and 12.7%, respectively, compared with blank cement. The used polymer improved slightly the pull-off force of the prepared cement, and 7 and 5% TPM−cement composites have the maximum values. All the proposed composites passed the impact testing without failure, where the combination between the polymer waste and silicate cement resulted in a stable composite surface. Compared with the blank, the different concentrations of TPM−cement composites show more stability against water absorption. In addition, the proposed composites and blank cement have a very low carbon dioxide emission. The ability to recycle the polymer waste, form new type of low-energy silicate, improve the mechanical and surface properties, uptake CO 2 gas, and reduce gas emission makes the proposed polymer waste mix−cement composites as environmentally friendly construction products.

“…Furthermore, an increase crystallinity % with the presence of CNT as displayed in the Table 2, is attributed to CNT play as a nucleating agent leading to faster crystallization and change in crystallinity % depending upon the increments in the filler concentrations. 33,34 All of the studied work before designated that CNT operated as nucleating agents, which induce easier and faster crystallization under isothermal and non-isothermal conditions. 35…”

“…It is perfect that with the presence of Nano filler in the polymer matrix leads to increase thermal stability means that crystallinity is firmly connected with the material mass loss. 44 Also, Figure 7 and Table 3 displayed the decomposition temperature and mass loss of WPE/WEPDM/0.5% CNT after irradiation. The thermal stability and residual weight of the nanocomposites increased with radiation doses up to 100 kGy.…”

Carbon nanotubes (CNTs) have established wide attention as strengthened fillers because of their excellent several characters. Nano polymers based on thermoplastic elastomer composed of waste polyethylene (WPE)/Waste ethylene propylene diene monomer (WEPDM) blended equally 50/50 wt. % and strengthened with different concentrations of CNT (0.1, 0.3, and 0.5%) were fabricated via melt mixing. The prepared specimens were exposed to various gamma radiation doses, namely 50 and 100 kGy to evaluate the impact of radiation on the Nano polymers structure. FTIR and XRD were used to track the structure and crystallinity changes of thermoplastic elastomer with CNT filling. Mechanical features including tensile strength (TS), elongation at break (E%), modulus of elasticity (EM) and hardness (Shore D) of the unirradiated and irradiated samples were evaluated. Furthermore, the dynamic mechanical properties named storage (E′) and loss modulus as well as tan delta (δ) of the fabricated specimens were measured. TGA and also DSC monitored the thermal decomposition and the melting point alterations caused by CNT reinforcement. Electromagnetic Interference (EMI) was studied for all fabricated samples as an application of shielding for radio frequency signals. In general, all the studied parameters revealed improvements of thermoplastic elastomer properties via CNT interference. Subsequent reinforcement of CNT concentrations into WPE/WEPDM produced higher shielding for radio frequency signals. Furthermore, applied gamma radiation doses improved the shielding properties of the fabricated nanocomposites.

Nowadays, due to environmental and reduction costs the plastics recycling industry applies new strategies to improve properties by mixing processed plastics with virgin polymers together with stabilizers, or compatibilizers, and chain extenders [10][11][12][13].

The paper presents the results of the ageing resistance of automotive mudfl aps made of recycled polyethylene blends. The mudfl aps were manufactured by a plastic sheet extrusion-calendaring process in Novotech Kostrzyn nad Odrą company. The changes of the mechanical properties in the tensile test and impact toughness test as well as in Shore hardness due to the accelerated aging process were characterized, taking into account the aging sensitivity coeffi cient (KI), and changes in the structure within the wavenumber range 4000-400 cm -1 , taking into account the CI coeffi cient. The results showed a higher melting point and crystallinity for the recycled HDPE blends during photo-oxidative degradation. Moreover, the results presented decreased tensile strength and ductility, due to macromolecular chain scission caused by oxidation. It was found that the blends of HDPE based on recycled materials are more sensitive to the aging process than virgin HDPE. Finally, it can be concluded that the sensitivity to ageing blends increases with the increase of recycled HDPE content in the HDPE matrix.
