“…The simulated currents for the PVDF/WS 2 , PVDF/WS 2 /0.15rGO, PVDF/WS 2 /0.3rGO, and PVDF/WS 2 /1rGO nanocomposite-based PENGs are 0.9 µA, 1.03 µA, 1.2 µA, and 1.09 µA, respectively, which lies at the range of the experimental results with the error bar. A good matching between the experimental results and simulated values provides the authenticity of the PVDF/WS 2 /rGO nanocomposite-based PENG performances [57].…”

The emergence of piezoelectric nanogenerators (PENGs) presents a promising alternative to supply energy demands within the realms of portable and miniaturized devices. In this article, the role of 2D transition metal dichalcogenide tungsten sulfide (WS2) and conductive rGO sheets as filler materials inside the polyvinylidene fluoride (PVDF) matrix on piezoelectric performances has been investigated extensively. The strong electrostatic interaction between C–F and C–H monomer bonds of PVDF interacted with the large surface area of the WS2 nanosheets, increasing the electroactive polar phases and resulting in enhanced ferroelectricity in the PVDF/WS2 nanocomposite. Further, the inclusion of rGO sheets in the PVDF/WS2 composite allows mobile charge carriers to move freely through the conductive network provided by the rGO basal planes, which improves the internal polarization of the PVDF/WS2/rGO nanocomposites and increases the electrical performance of the PENGs. The PVDF/WS2/0.3rGO nanocomposite-based PENG exhibits maximum piezoresponses with ∼8.1 times enhancements in the output power density than the bare PVDF-based PENG. The mechanism behind the enhanced piezoresponses in the PVDF/WS2/rGO nanocomposites has been discussed.

This study aimed to explore the influence of film thickness on the piezoelectric efficiency of polyvinylidene fluoride/graphitic carbon nitrate nanosheet (GCN) composite films, taking into account the effect of GCN alignment. Our findings demonstrated that the piezoelectric performance of these films was markedly dependent on their thickness. We have observed a direct relationship between film thickness and piezoelectric efficiency, with thicker films showing a greater capability to convert mechanical pressure into electric energy. This increased efficiency is attributed to the enhanced ability to thicker films to distribute stress uniformly across the material, which is crucial for optimizing the piezoelectric effect. Our results advance the understanding of how variation in film thickness impact mechanical properties such as stiffness and flexibility, which subsequently affect the piezoelectric response. Through predictive modeling, we analyzed the mechanical dynamics of film displacement under an electrical potential and clarified how different thickness influenced the mechanical properties and piezoelectric output. This detailed analysis deepens the fundamental understanding of material design for optimal piezoelectric performance and underscores the critical role of film thickness in engineering application.
