Fig. 1: Dielectric properties of HEP-B1 and HEP-B2 polymer blends and individual polymers.

a Molecular structures of the individual components used in HEP-B1 and HEP-B2, including PVDF, P(VDF-TrFE), P(VDF-HFP), PP, and PS, are depicted alongside a conceptual illustration of the blended polymer matrix. b Frequency-dependent dielectric constant and loss tangent of HEP-B1, HEP-B2, and their components, compared with the rule-of-mixture (RoM) predictions (RoM-B1 and RoM-B2). c Influence of varying PS content on dielectric properties in polymer blends.
