Microwave radiations effect on electrical and mechanical properties of poly (vinyl alcohol) and PVA/graphene nanocomposites

Development of Electromagnetic Shielding Material from Conductive Blends of Polyaniline/Polystyrene‐isoprene‐styrene Copolymer

“…The conductivity of all blends was measured from C−V curves by relationship: [34] …”

Trends on Synthesis of Polymeric Nanocomposites Based on Green Chemistry

“…It is worth mentioning that the irradiation time is an important control variable of this process, since the PNCs properties increased from 5 to 10 min, but from 20 min to up, the PNCs was thermally degraded, due to the high concentration of NPs [102,103]. For example, in the graphene-polyvinyl alcohol PNCs, it was observed that specimens (20 wt.% of graphene) were incinerated in the first 5 s of irradiation [104]. The thermal degradation of PNCs has not been studied in detail, and it is worth a topic to address the limitations of this technology.…”

Characterization of network bonding created by intercalated functionalized graphene and polyvinyl alcohol in nanocomposite films for reinforced mechanical properties and barrier performance

“…As such, graphene is not easy to disperse in PVA, and improving the performance of PVA is difficult. Afzal [36] reported that the tensile strength of PVA loaded with graphene was even worse than performance of PVA. Therefore, most studies deal with nanocomposites of PVA with GO.…”

“…Graphene oxidizes at a temperature as high as 400 • C. It has exceptional mechanical properties and thermal conductivity, superhigh specific surface area, and outstanding barrier properties [35]. There are a number of studies on the preparation of composites from graphene and PVA [36][37][38]. But the graphene mentioned in the studies on improving the mechanical properties of PVA is mostly in the form of graphene oxide (GO), and not the real graphene, because graphene is incompatible with PVA; it is difficult to disperse graphene in the substrate.…”
