Effect of ionic liquid functionalized carbon nanotubes on mechanical, thermal and electrical properties of carbon nanotubes-reduced graphene oxide/PMMA nanocomposites

Impact of Ionic Liquid on the Dielectric and Mechanical Performance of Poly(Vinyl Chloride) (PVC)/Reduced Graphene Oxide (RGO) Nanocomposites

“…It is known from literatures that the dielectric permittivity of a system is determined by the number and availability of orientable dipoles under the applied electric fie. [ 19,21,31 ] Normally at low frequencies most of the dipoles in composites are able to align with the field and at higher frequencies they cannot orient themselves because they are not getting enough time to orient. Therefore the dielectric constant decreases with increasing frequency.…”

“…The exfoliation in graphite using IL is also reported by some research groups. [ 20–22 ] IL liquid can be strongly adsorbed on the graphene sheets forming a charged diffused layer. These charged layers may produce the coulombic repulsion forces between graphene sheets and hence make the oxidized graphene sheets easily separated and overcome the strong van der Waals’ force of attraction between the layers.…”

Effect of ionic liquids on thermomechanical properties of polyetheretherketone‐multiwalled carbon nanotubes nanocomposites

“…The enhanced thermal resistance of the synthesized nanocomposites was due to the higher T m values. The findings revealed that the welldistributed MWCNTs functioned as effective nucleating agents, [36][37][38] allowing PEEK crystallization to occur quickly. A similar effect was discovered in recent research, which showed an improvement in the thermal properties of polyvinylidene fluoride/multiwalled carbon nanotubes/ionic liquid (PVDF/MWCNTs/IL) nanocomposites.…”

“…This phenomenon was discovered indicating the presence of IL in nanocomposites at greater concentrations, which prompted plasticization. 38 The modulus of elasticity is among the most important factors to consider when evaluating PEEK nanocomposites for biomedical engineering applications as a substitute for human bone fixation devices. Figure 7b depicts the elastic modulus-contact depth profiles of PEEK nanocomposites, and the related parameters were summarized in Table 2.…”

“…51 Also, the flexible polymer ring mobility and plasticizing effects of ILs decreased the activation energy and thermal stability of polymer composites when the amounts of ILs were more than 1 wt%. 38,52 exhibited enhanced thermomechanical characteristics for biomedical applications compared to [EMIM]Ac. The present finding could be beneficial for the recognition of ILs assisted benign processes for PEEK/MWCNTs nanocomposites preparation as the quantity of IL used is a key aspect for its commercial viability.…”
