Abnormally enhanced dielectric permittivity in poly(vinylidene fluoride)/nanosized-La2NiO4−δ films

- Significantly improved dielectric properties were successfully achieved in LNO/PVDF.
- Good flexibility of high permittivity LNO/PVDF nanocomposite was also achieved.
- Large interfacial area of nanosized filler caused improved dielectric properties.
- Modified-surface LNO particles was also the primary cause of improvement.
