  Spin Coated Polyvinylidene Difluoride / Ionic Liquid Nanocomposite Thin Films with Enhanced Dielectric and Piezoelectric Properties

  By Kavita Rani, Anurekha Sharma, Yashashchandra Dwivedi

  Abstract: This study introduces a novel approach to enhance the piezoelectric and dielectric properties of polyvinylidene difluoride (PVDF) by incorporating 1-butyl-3-methylimidazolium tetrafluoroborate ([BMIM][BF₄]) ionic liquid via a spin-coating method— a processing route that has been rarely reported for PVDF/ionic liquid composites. Structural and morphological analyses using X-ray diffraction (XRD), Raman spectroscopy, Fourier-transform infrared spectroscopy (FTIR), and scanning electron microscopy (SEM) confirm the successful integration of [BMIM][BF₄] into the PVDF matrix. The …
