“…Some bands can be used to differentiate the trans and gauche rotational isomers, characteristic of the crystalline and amorphous regions in PET. The peaks at 1339 and 1378 cm −1 represent the fraction of the glycol segment in the trans and gauche conformations, respectively [ 18 , 19 ]. According to Figure 1 , the gauche conformation responsible for amorphous content in PET occurred to a much greater extent.…”

The paper investigates the synthesis of green composites and their properties before and after the laboratory accelerated aging tests. Materials were made of unsaturated polyester resins (UPRs) based on recycled poly(ethylene terephthalate) (PET) and wood flour (WF). The effect of dibenzylideneacetone (dba) addition on mechanical and thermomechanical properties was also determined. Green composites were obtained using environment friendly polymeric cobalt as an accelerator. Before and after exposition to the xenon lamp radiation, the UPRs physically modified by WF were characterized only by a greater flexural modulus compared with the analogous composites based on the pure resin. Addition of dba caused the increase of flexural modulus, flexural strength, strain at break and mechanical loss factor compared to the non-modified material. After aging only the last mentioned parameter took on lower values compared to the pure resin analogues.

In this review article, we have presented for the first time the new applications of supercapacitor technologies and working principles of the family of RuO 2-carbon-based nanofiller-reinforced conducting polymer nanocomposites. Our review focuses on pseudocapacitors and symmetric and asymmetric supercapacitors. Over the last years, the supercapacitors as a new technology in energy storage systems have attracted more and more attention. They have some unique characteristics such as fast charge/discharge capability, high energy and power densities, and long stability. However, the need for economic, compatible, and easy synthesis materials for supercapacitors have led to the development of RuO 2-carbon-based nanofillerreinforced conducting polymer nanocomposites with RuO 2. Therefore, the aim of this manuscript was to review RuO 2-carbon-based nanofiller-reinforced conducting polymer nanocomposites with RuO 2 over the last 17 years.

“…Contrary to CNTs, studies on the effects of different radiation sources on GNPs report the formation of topological defects such as the ejection of multiple atoms and consequent formation of vacancies [ 32 , 33 ]. However, improvement of radiation resistance, less crystal defects and self-healing mechanism of radiation-induced defects are also observed in GNP nanocomposites by many authors [ 34 , 35 , 36 , 37 , 38 ]. Overall, only few experiments with preliminary results have been conducted to investigate the radioprotectant properties of carbon-based polymer nanocomposites, and the impact of radiation on PE nanocomposites is still unknown.…”

Impact of Proton Irradiation on Medium Density Polyethylene/Carbon Nanocomposites for Space Shielding Applications

et al. 2023

The development of novel materials with improved radiation shielding capability is a fundamental step towards the optimization of passive radiation countermeasures. Polyethylene (PE) nanocomposites filled with carbon nanotubes (CNT) or graphene nanoplatelets (GNP) can be a good compromise for maintaining the radiation shielding properties of the hydrogen-rich polymer while endowing the material with multifunctional properties. In this work, nanocomposite materials based on medium-density polyethylene (MDPE) loaded with different amounts of multi-walled carbon nanotubes (MWCNT), GNPs, and hybrid MWCNT/GNP nanofillers were fabricated, and their properties were examined before and after proton exposure. The effects of irradiation were evaluated in terms of modifications in the chemical and physical structure, wettability, and surface morphology of the nanocomposites. The aim of this work was to define and compare the MDPE-based nanocomposite behavior under proton irradiation in order to establish the best system for applications as space shielding materials.
