Effect of gamma irradiation on the electrical and optical properties of PEVA composite membrane embedded with conductive copper fluoroborate glass powder

“…Moreover, the bands assigned to the PEVA polymer agree with previously published reports. [2][3][4][5][6][7] The peak intensity did not change as the amount of the dopant increased. This can be due to the good dispersion and distribution of the dopant inside the PEVA matrix.…”

“…Compared with the irradiated samples, the bandgap energy E g for the virgin polymer sample (PEVA) decreased from 4.12 eV to 3.85 eV. However, all other samples were influenced by the radiation, as shown in Table (3).…”

“…Because of their high tensile strength, ease of preparation, low cost, and flexibility, polymers are good candidates for many industrial applications. [1][2][3] Conductive polymer-glass composite films have gained great attention owing to their excellent dimensional stability, safety, manufacturing simplicity, electrochemical characteristics, and processability. [4][5][6] However, the use of polymer sheets faces some limitations as they have low ionic conductivity.…”

“…Inorganic additives were used with polymers not only to improve electrical properties but also to improve mechanical properties and increase thermal stability. 8 The electrical conductivity of many polymers including polyethylene glycol (PEG), 9 polyvinyl pyrrolidone (PVP), 10 polyvinyl chloride (PVC), 11 and polyvinyl alcohol (PVA) 12 has been improved by the addition of inorganic metal oxides such as copper, titanium, aluminum, and lithium. 13,14 In our previous research work, polyelectrolyte membranes based on phosphorylated-PVA/cellulose acetate were investigated for direct methanol fuel cell applications 15 by doping oxidized cellulose with Bi 0.5 Na 0.25 K 0.25 TiO 3 films fabricated for optoelectronic application.…”
