Free‐Volume Regulation Enables Significantly Enhanced Electrical Breakdown via Short‐Chain Molecular Spatial‐Positioning Intercalation into Poly(vinylidene fluoride)

Advanced Science, EarlyView.
An innovative molecular spatial‐positioning shimming strategy is developed to optimize the electrical properties of poly(vinylidene fluoride) (PVDF). By intercalating polyethylene wax (PE wax) short‐chain molecules into PVDF's free volume, the film achieves a significantly enhanced energy density of 32.67 J cm−3.
