The dielectric properties of poly(vinylidene fluoride) (PVDF) polymer incorporating with silver (Ag) nanoparticles, which were successfully prepared via a hydrothermal method using Aloe vera plant-extracted solution as surface stabilizer and reducing agent (Ag@Ale-NPs), were investigated. Ag@AleNPs/PVDF polymer nanocomposites were prepared by a liquid-phase assisted dispersion and hot-pressing methods. The microstructures of the Ag@Ale-NPs and Ag@Ale-NPs/PVDF nanocomposites were characterized. The modification of the Ag@Ale-NPs surface was confirmed using X-ray photoelectron spectroscopy. Interestingly, by using a filler volume fraction of 0.18, the composite exhibited a high dielectric permittivity of approximate to 92.5 with very low loss tangent of 0.049 at room temperature and 1 kHz. With further increasing a filler volume fraction to 0.22, a greatly enhanced dielectric permittivity of approximate to 257.2 was obtained with low loss tangent (tan delta approximate to 0.26). Excellent dielectric properties of the Ag@Ale-NPs/PVDF nanocomposites were described by the interfacial polarization effect and the formation of micro-capacitor in the PVDF polymer matrix.
