Abstract

Electromagnetic pollution and cancer are phenomena essentially endangering the future of humanity. Herein, research with multiple approaches has proposed lonely solving the aforementioned issues. The recent literature has demonstrated that...

Plasma Engineering toward Improving the Microwave-Absorbing/Shielding Feature of a Biomass-Derived Material

“…Evidently, CO 2 treatment boosted the polarization types as a result of the emergence of various defects by exhausting the coupled oxygen- and nitrogen-containing functional groups and rearranging the chemical species, elevating the dipole polarization types; meanwhile, the reductive process under the H 2 /Ar atmosphere reduced the polarization intensity compared to the Ar-treated sample. This phenomenon originates from the reduced acidic functional groups and prolonged conjugated structures in the bioinspired structure. − The straight line confirms that the conductive loss is the vital microwave absorption mechanism of the carbonized structure as a result of the developed conjugated structure in the pyrolysis situation. However, exhausting and eliminating the heteroatoms by CO 2 and H 2 plasma mitigate the dipole polarization types and intensities.…”

Enhanced electromagnetic wave absorption and mechanical performances of graphite nanosheet/PVDF foams via ice dissolution and normal pressure drying

“…plays a pivotal role as a carrier for the EM absorbing filler. 33–36 Seyedian et al successfully synthesized MgFe 2 O 4 nanoparticles exhibiting diverse phases and morphologies, and subsequently integrated them with a polyethylene terephthalate matrix to significantly bolster the absorbing capabilities. 37 Among them, polyvinylidene fluoride (PVDF), as a thermoplastic polymer, is known for its corrosion resistance and high dielectric constant, along with recyclability.…”
