AbstractA novel all-polymeric material with high dielectric constant (k) has been developed by blending poly(vinylidene fluoride) (PVDF) with polyacrylamide (PAM). The dependence of the dielectric constant on frequency and polymer volume fraction was investigated. When the weight fraction of PAM is 1wt%, the dielectric constant of the blend could be up to 24, and the dielectric loss tanδ can be lowered to 0.06. The SEM investigations suggest that the enhanced dielectric behavior originates from significant interfacial interactions of polymer-polymer. XRD and FTIR demonstrate that blending PAM with PVDF affects the crystalline behavior of each component. Our finding suggests that the created high-k polymeric blends represent a novel type of material that are flexible and easy to process, and is of relatively high dielectric constant and high breakdown strength; moreover find applications as flexible electronics.
