Storage modulus (a) and Loss tangent (b) as a function of temperature with a frequency of 5 Hz for the PVDF matrix with 3 wt% of SiO₂, SiO₂-vinyl, and F-SiO₂, respectively. Storage modulus (c) and Loss tangent (d) as a function of temperature with a frequency of 5 Hz for the PVDF matrix with 3 wt%, 5 wt%, 20 wt%, and 35 wt% of F-SiO₂, respectively. These results were obtained by dynamic thermomechanical analysis (DMA).
