摘要：

The present work involves dielectric properties of PVDF/TiO2 and PVDF/TiO2/Clay nanocomposite synthesized via solution casting technique. The increased nucleation density attributed to PVDF, TiO2 and Cloisite® 30B NPs causes oriented planes that improve the crystallinity of the resultant nanocomposites. The morphological images prove the uniform deposition of TiO2 and Cloisite® 30B NPs in the ternary nanocomposite. Improved roughness of ternary nanocomposite is observed in AFM images causing huge charge-storing properties in the polymer-based nanocomposite. The highest ε' of PVDF/TiO2 and PVDF/TiO2/Clay nanocomposites are achieved as 2 × 103 and 1.4 × 104 at 1 kHz, respectively. The maximum ε′′ of PFTC-6 nanocomposite is found to be 4.04 at 1 kHz. This giant permittivity of the prepared ternary polymer-based nanocomposite could be a great pathway for the electronic industry. The PVDF/TiO2 nanocomposite shows maximum σac conductivity of 5.16 × 10−4 S/m and 5.87 × 10−4 S/m at 1 kHz and 3 MHz, meanwhile the PVDF/TiO2/Clay nanocomposite shows maximum σac conductivity of 3.37 × 10−3 S/m and 5.16 × 10−3 S/m at 1 kHz and 3 MHz, respectively. The high thermal stability and excellent dielectric behaviour of PVDF/TiO2/Clay nanocomposite prove its worth towards high performance in charge storage and electronic applications. © 2025 Elsevier Ltd
