“…It was reported that the maximum charge density ( σ ′) of triboelectric material highly depends on the dielectric constant. 42–45 where σ 0, x ( t ) and d and are the triboelectric charge density at the equilibrium state, gap distance (2 mm in present case), and thickness. Therefore, it is clearly visible that the dielectric constant can increase the charge density and thus the performance of RTNG is increased.…”

“…CQDs hydrothermally synthesized from paddy straw were used as nano-reinforcements in the fabrication of nanocomposites [90]. Stone waste particle nanocomposites reinforced with CQDs were fabricated and showed high strength, with an increase of up to 58% as compared to those without CQDs (Figure 7a).…”

Carbon nanomaterials are an emerging class of nano-reinforcements to substitute for metal-based nanomaterials in polymer matrices. These metal-free nano-reinforcement materials exhibit a high surface area, thermal stability, and a sustainable nature. Compared to conventional reinforcements, nano-carbon-reinforced polymer composites provide enhanced mechanical and thermal properties. While previous reviews summarized the functionality of nanocomposites, here, we focus on the thermomechanical properties of nano-carbon-reinforced nanocomposites. The role of carbon nanomaterials, including graphene, MXenes, carbon nanotubes, carbon black, carbon quantum dots, fullerene, and metal–organic frameworks, in polymer matrices for the enhancement of thermal and mechanical properties are discussed. Different from metal-based nanomaterials, carbon nanomaterials offer high specific strength, abundance, and sustainability, which are of considerable importance for commercial-scale applications.

“…Ongoing progress is being made toward the manufacture of more flexible dielectric nanocomposites, which can lead to distinctive designated technologies [1]. The nanocomposites films were created by dispersing nano-sized inorganic additives in an organic polymeric matrix [2]. Those composites have been employed in a variety of implementations, such supercapacitors as well as stretchy electrodes [3].…”

Different contents of manganese oxide (MnO2) and zinc oxide (ZnO) were combined with polyvinyl alcohol (PVA) to form flexi MnO2/PVA as well as ZnO/PVA nanocomposite films. XRD as well SEM methodologies are used to evaluate the properties of the fabricated films. The XRD analysis demonstrates that MnO2/PVA as well as ZnO/PVA composites were effectively fabricated. The SEM pictures show that MnO2 and ZnO are uniformly dispersed throughout the PVA polymeric chains. Furthermore, the electrical conductivities, dielectric permittivity, electric moduli behaviors, as well as dielectric impedances of PVA, MnO2/PVA, ZnO/PVA films were recorded using LCR method in frequencies 102 to 106 Hz. At 105 Hz, the dielectric enhanced from 2.05 for PVA to 5.5 on PVA/5%ZnO and 4.15 for PVA/10%MnO2, while the conductivities increase from 1.05x10-7 S/cm for PVA to 4.01x10-7 S/cm for PVA/5%ZnO and to 5.4x10-7 S/cm for PVA/10%MnO2. The current work pave the way to using of ZnO/PVA and MnO2/PVA flexi nanocomposite films in a different uses including battery, super-capacitors, as well as storage devices.
